Setting Up the LX100 Part 3 Setup and Rec Menus


LX100


The first Menu  to tackle is Setup even though it is the fourth of five menus listed.
As usual, please regard my comments as informative not prescriptive. Each individual has his or her own ideas about the way they want a camera to work. The LX100 offers many options so the camera can be configured to personal preference.

As we go through the menus I will refer only to those items about which I think I can offer helpful information not readily available in the operating instructions.

Procedures for Wi-Fi are well covered in the operating instructions.

BeepThere are three submenus, Beep Volume, Shutter Vol. and Shutter Tone.
The settings are largely self explanatory however I just point out that the shutter sound is made up of both a real sound (in the case of the mechanical shutter) and an artificial sound. The Shutter Vol. tab just affects the artificial sound.

With this artificial sound switched off the mechanical shutter is very quiet, often inaudible if there is a moderate amount of noise in a room.

Live View Mode  This appears to be a refresh rate option, but it is not clear whether it applies to the EVF, Monitor or both. The options are 60fps and 30 fps, with the higher rate said by Panasonic to give smoother panning at the cost of slightly higher battery drain.

I set 60 fps and still get good battery life.

Monitor Display [NOTE: This changes to Viewfinder when you look in the viewfinder, upon which adjustments apply to the EVF]

Both are highly adjustable.

After considerable experiment I currently have the following settings.
Parameter
Monitor
EVF
Brightness
0
-1
Contrast
0
-3
Saturation
0
-2
Red Tint (R/G)
0
-1
Blue Tint (B/Y)
0
0


Each individual has their own preferences for the displays. The amount of adjustment on offer should keep everybody happy.

Some early reviews of the LX100 made negative remarks about the EVF as being over contrasty and saturated with blocked up shadows. At default settings I would agree. However I suspect some of these reviewers simply failed to realise that the EVF is adjustable.

Monitor Luminance  You get three manual settings and Auto.  I just set Auto. There are so many  things to adjust I don’t need another one.

Sleep Mode  I just leave this at 5 minutes which I think is the default.

USB Mode  I have never used this so I have no advice.  Likewise TV Connection although the options appear self explanatory.

Menu Resume  This is handy. There is, unfortunately,  no user selectable “My Menu”. However Menu Resume is a reasonable second best. Set Menu resume ON  and the camera will jump to the last used menu item when the Menu/Set button is pressed.

Menu Background  There are several options here. I use the second one from the top.

Menu Information  When ON, this displays a moving banner of information about the current menu item across the top of the screen.  I suggest you leave this ON until you are familiar with all the menu items then switch it OFF to declutter the screen.

Version Disp  Shows what firmware version is installed.

Self Timer Auto Off  This is very useful. When set to ON the self timer will be automatically turned OFF when the camera is powered off. This is for all those people like me who forget to turn off the self timer.

Now we come to the Rec Menu

Photo Style 
Here you make decisions which determine the appearance of JPG images coming off the camera.

You can scroll across the options at the top of the screen. These are presets such as Standard, Vivid, Natural, Mono……………etcetera.

Or you can scroll down from any of the presets and adjust individual image parameters, creating a 
Custom Photo Style. I have created one of these under the [Standard] tab, as below:

The rationale behind these is that the Standard JPGs tend to produce mushy looking details apparently due to a high default level of noise reduction. In addition JPG colors are often exaggerated and contrast high.

Contrast -2
Sharpness +3
Noise Reduction -5
Saturation -2

Even at these settings the JPG colors are rather exaggerated and sometimes inaccurate. Some people like that.  For me these settings are a work in progress.

Picture Size
You can set L [approx. 12 Mpx], M [approx. 6.5 Mpx] of S [approx. 3 Mpx].
I see little reason to set anything less than L.  It’s not as though there is an over abundance of pixels even at L.

Quality
This is a good one to locate on a Fn button or the Q Menu. The camera can capture JPG, RAW or both.

Note that if you want to evaluate sharpness on the monitor or in the EVF when reviewing images it is desirable to shoot JPG (fine) + RAW so you have a high resolution JPG to review. If you just shoot RAW the camera creates a very low res JPG for the EVF and monitor.

AFS/AFF/AFC (AF Single, AF Flexible, AF Continuous) Page 114 of the Instructions.
There has been some discussion on user forums about which setting is best.

With AF Single if the shutter button is half pressed the camera focusses and locks focus while the shutter button is held half pressed. The AF box goes green, a green focus dot appears top right on the screen and there is a quick double beep focus confirmation.

With AF Continuous a half press on the shutter button brings up the green AF box, green dot upper right and quick double beep but focus does not lock. Instead the camera keeps continuously refocussing. With a still subject you can see this most easily at the edges, where the preview image appears to pulsate.  In a quiet room you can hear the focus motor running continuously, hunting back and forth.

AF Flexible works like AFS when the subject is still.   But if the camera detects subject movement it will switch to focus behaviour which is similar to but not the same as AFC.   The camera will refocus then stop.  If movement continues the camera will again refocus and stop.  The refocussing is intermittent.

You can demonstrate this for yourself by moving the camera towards and away from the subject to simulate subject movement.

I use either AFS or AFC which is probably because I like to feel as though I am in control of proceedings.

Other users have reported they use AFF and are happy with that.

I can only suggest you experiment.

Metering Mode
There are three choices, Multiple (a.k.a. Nikon Matrix, Canon Evaluative), Center Weighted and Spot. 

There are plenty of websites which provide tutorials on the pros and cons of each.  Here is one https://photographylife.com/understanding-metering-modes  

Cambridge in Colour also has a section on metering.

My practice is to use Multiple Metering all the time and to apply exposure compensation if the subject requires this.  

One sure fire way to get a lot of incorrect exposures is to routinely use Spot Metering. That should be kept for special circumstances and even then requires very careful management.

Burst Rate 
The choice is between S(uper) H(igh), H(igh), M(edium) and L(ow).  Pages 142-144 of the Operating Instructions.

Super High is only available with the E-Shutter selected.

The fastest rate which allows image preview and focus on each frame is M, which is nominally 6.5 frames per second, but on my tests actually provides a variable rate depending on the subject, Quality (JPG/RAW) and exposure settings.
SH or H might be useful for monitoring a golf swing, for instance. M is most useful for catching moving subjects such as children, together with AFC.

Note the list of exclusions and possible causes of slow frame rate listed on Pages 142-144.

Auto Bracket
The camera can fire a series of shots in pre set exposure steps, usually on a tripod to ensure each frame is exactly in registration with the others.   This is to facilitate subsequent blending of the frames in Photoshop or similar image editor.

Unfortunately as per long standing Panasonic practice the camera will not allow Timer Delay and AEB to be combined.
So you have to physically press and hold the shutter button and hope the camera does not move during the exposure sequence OR use a cable shutter release OR actuate the shutter via a smart phone.

The three sub menus are
1. Single/Burst  If set to Single you have to actuate the shutter for each exposure of the sequence.
If set to Burst you have to press and hold down the shutter for the duration of the exposure sequence.
2. Step  This ranges from 3 shots each 1/3 stop apart to 7 shots each 1 stop apart.  There should be enough  here  for just about everybody although I have read complaints from some users wanting more, for what purpose I cannot imagine.
3. Sequence Take your pick.

I set Burst, 5 exposures at 1 stop intervals and -/0/+ sequence.

I have to confess however that I hardly ever use AEB as I am not a fan of the results produced by the Merge to HDR function in Photoshop.  I find it much easier and the final image usually more satisfactory if I simply use RAW capture and Adobe Camera Raw.

Highlight/Shadow
This provides a way to tweak the tone curve of JPG images prior to capture. I have never thought the feature necessary or useful and have never seen a post about it in user forums.
I suspect Panasonic’s engineers included it because they can.

i-Dynamic 
however is definitely useful for JPG images especially when subject brightness range is high and there is a risk of blown highlights.  

i-Dynamic uses less exposure than normal (to protect the highlights)  then applies a tone curve correction to bring up the low and middle tones.
You have to choose between Auto, High, Standard, Low and Off.

I set Auto and leave it there permanently. My tests have shown that the effect is the same as High when it needs to be.

i-Resolution
Having tried this at various times I am yet to be convinced that i-Resolution has something beneficial to offer. (JPGs only).

Simultaneous record w/o filter  Pages 89-99 of the Instructions.
Did someone request this?  Who knows ?

The menu item is greyed out until you press the Filter button. If the feature is On the camera captures two versions of the photo with one exposure, one version with  the effect,  the other without the  effect.

Note that because the LX100  lacks a Mode Dial the filter function works differently from that on a camera with a Mode Dial, for instance the FZ1000.

On the FZ100 the filter effect is easily switched on and off  simply by turning the dial.

On the LX100 pressing the filter button enters the filter menu but pressing the button again does not exit the menu. You have to scroll back to [No Effect] in the filter menu to make pictures without the filter effect.

i-Handheld Night Shot  Page 78 of the Instructions.
This fully automatic (JPG only) function only works in [iA] Mode and the menu item is only accessible in [iA] Mode.

If set to ON the hand held camera detects both low light levels and camera movement. It makes multiple captures in quick succession then combines the in camera with the hope that by so doing the effects of camera shake will be reduced.
I have never used this function but maybe someday…………

i-HDR  Here is another fully automatic, [iA] Mode, JPG only function which, if  high subject brightness range is detected fires three exposure bracketed shots in quick succession and combines them in camera.

I have tested this function and it works, producing decent results.

I think [iA] users could probably leave [i-Handheld Night Shot] and [i-HDR]  set ON permanently. They only self activate when required.  Both are automatically disabled when one of the P, A, S, M Modes is engaged.

HDR   Page 112 of the Instructions.
This is like [i-HDR] but it works in the P, A, S, M  Modes when JPG Quality is set (not JPG+RAW).  
Three exposure bracketed shots are taken in quick succession and combined in camera to output one file.

Setup options include the amount of bracketing (Dynamic Range), Auto Align (On/Off) and feature On/Off.

 I have tried the feature. It works.  I use the maximum DR setting available (+/- 3 EV) and Auto Align ON.

Having said that I mostly use RAW capture which in most cases allows me to get an even better result. But for the user who just does JPG  capture,  HDR could be useful.

Multi Exp Page 159 of the Instructions.
This works with RAW or JPG capture. The instructions are explicit and seem easy enough to follow.

I have yet to find a use for this feature. Maybe I lack the requisite imagination.
Time Lapse Shot  and  Stop Motion Animation  are well described on Pages 153-158 of the Instructions. I have no experience with these features.

Panorama Direction  Pages 150-152 of the Instructions.
This is the place to set Panorama sweep direction. To activate the Panorama function enter Drive Mode, which is best allocated to the Q menu or a Fn button. I have it on Fn1.

If the Panorama Symbol is greyed out in Drive Mode this indicates an incompatible setting elsewhere. This could be RAW or JPG + RAW Quality or HDR in the Rec Menu.

There are 4 options for sweep direction, left/right and up/down. Each works in landscape or portrait orientation, giving a total of 8 sweep options.

Some practice is recommended. Follow the arrows as indicated on screen.

Shutter Type
On Micro Four Thirds camera this is a big deal because the spring loaded focal plane shutter on many of these cameras causes unsharpness due to shutter shock.  With Panasonic M43 cameras such as the GH4 I routinely use the electronic shutter for all general photography.

However the LX100 uses an in lens diaphragm type mechanical leaf shutter which is very quiet and never causes shutter shock. Even better it uses electronic commencement to each capture, completely eliminating shutter induced vibration prior to or during exposure.

So with the LX100 the mechanical shutter can be used all the time with no ill effects.
The only reason I can think of for using the electronic shutter would be to access the ultra fast  speeds, from 1/5000 to 1/16000.

Some owners might be concerned about wearing out the mechanical shutter. Panasonic does not, as far as I am aware, provide a service life estimate for the leaf shutter.

Flash  Pages 180-186 of the Instructions.
The problem with this camera’s flash is that it is not built in. This is sufficient disincentive for me that I never use the flash and never put it in the carry bag.

This is a pity as the flash appears to be quite capable including the ability to operate as a commander for multiple wireless off camera units.

ISO Limit Set 
This determines the upper limit which the camera will set in Auto ISO.  I use 12800 as 25600 is really not useful in my view.

ISO Increments
Aperture and shutter speed are available in 1/3 stop increments, so I set ISO to whole stops. 1/3 stop ISO settings seems like overkill to me.

Extended ISO
This allows manual ISO settings down to 100 to be set. Auto ISO will still use 200 as the lowest setting however.

There has been some discussion on user forums about aspects of image quality at ISO 100. However DXO Mark has posted results showing  ISO 100 to have slightly better signal to noise and dynamic range figures than ISO 200, so I see no reason to avoid ISO 100 in bright light or on a tripod.

Long Shtr N(oise) R(eduction) 
The camera has a set of algorithms such that at some settings of  ISO and long shutter openings, noise is automatically removed in a process which requires twice the original exposure time. This means that if the exposure is, say 20 seconds the NR function requires another 20 seconds before the camera is ready for the next exposure.

i-Zoom and Digital Zoom  (Electronic virtual zoom functions)
These are both JPG only digital zoom functions.   i-ISO is activated when either is used.
I-Zoom allows virtual zoom to focal length E150mm and retains control of the AF box.

Digital Zoom goes out to E300mm but uses a  fixed large AF box. There is obvious deterioration of picture quality even on the monitor at the limit of Digital Zoom.
I have not used either of the electronic virtual zooms on the LX100.  However I experimented with them quite extensively on the FZ1000 and found that shooting RAW and cropping gave better results.

Color space
There has been some discussion about this on user forums. The usual advice given in photo books and tutorials is to set Adobe RGB as this provides a larger color gamut.  However the sRGB setting may be better for images which are not destined for high output printing, which I imagine would be the great majority.

Stabiliser
Allocate this to a quick access portal. I have it on the Q Menu.

My usual practice is to leave the stabiliser on the top setting (Normal) for all general hand held photography and to switch it OFF when the camera is on a tripod.  There is also a Panning setting which I have not used as the camera is not one which will generally be used for sport/action.

Face Recognition and Profile Setup appear to be for gimmick tragics.  Those camera users who can never have too many features and frills  no matter how dubious their merit.

No wonder people yearn for a camera without all this fairy floss.

Setting up the LX100 Part 2 Q Menu and Buttons


LX100


Several buttons on the LX100  can have user selectable functions.

AF/AE-Lock Button  Custom Menu Screen 1/9.

There are four options for this versatile button within easy reach of the right thumb. These are AE Lock, AF Lock, AF/AE Lock and AF ON.

The option you select will depend very much on your style of camera use and your experience with the use of this particular button.  I recommend spending some time experimenting with the effect of each option and also the way in which the AF/AE Lock button and the AF/AE-Lock Hold function interact.

In the past, particularly with Micro 4/3 cameras and the FZ1000, I would set AF-ON to separate AF (on the back, AF/AE-L, button) from Auto Exposure and capture (on the front, Shutter, button).  When AF-ON is set as the selected function the AF/AE-Lock Hold tab is greyed out.

This enables activation of AF Single and also AF Continuous from the back button.  But I found little use for this on the LX100 which is not the type of camera which finds much use for sport/action.

So I now have the button set to AF-Lock.  I also have AF/AE-Lock Hold (next tab down on Screen 1/9 of the Custom Menu) set to ON.

When I want to make a series of exposures of a subject each focussed in the same place, I  move the AF box to the part of the frame I want in focus then press the AF/AE Lock button. This locks focus on the chosen area and holds focus while a series of photos is made.

iA Button  This is easily bumped inadvertently when switching the camera on and off. So go to the Custom Menu, Screen 8/9 and scroll down to the [iA Button Switch] tab. Set [Press and Hold]. Now an accidental bump will not activate the button which has to be held down for a little less than one second to activate.

Video Button  If you shoot video leave this active, obviously. Users who only shoot stills can disable the button to prevent unintentional activation, Custom Menu,  Screen 8/9.  Unfortunately the button cannot be re tasked and neither can the Filter Button which I find disappointing as I have no use whatsoever for the filters.

I discussed operation of the Cursor buttons and Direct Focus Area in the previous post.

Playback and Disp  buttons have set functions.

Now we come to the Function Buttons

The function of each of the three Fn buttons is user selectable from a long list of options on Page 38 of the Operating Instructions for Advanced Features.

This might appear a bit daunting at first as there are about 64000 combinations available.

So, I suggest you first look at the default function for each button.

Default for Fn1 is [Preview], Page 88 of the Operating Instructions. I definitely recommend using Fn 1 for a more useful purpose as I do not find [Preview] even slightly useful.

Default for Fn2 is Wi-Fi. This cannot be allocated to the Q menu so if you want Wi-Fi it has to be on a  Fn button and Fn 2 is as good as either of the others.

Default for Fn 3 is [LVF/Monitor Switch]. I definitely recommend going to the Custom Menu, last tab on the list, Screen 9, [Eye Sensor].

Set Sensitivity to LOW.

Set [LVF/Monitor Switch] to LVF/Mon AUTO.

Now the monitor will display when you look at it and the viewfinder will display when you look in there. And you can use the Fn 3 button for something else.

Deciding priorities 

The idea is to allocate more frequently used items to a Fn button (quicker access) and less frequently used items to the Q Menu (at least one more button press is required for access).

Nobody can tell you what are your personal preferences and if you are a newcomer to this style of camera you will probably not yet be aware of them yourself.

Experiment is required.  Trawl through the list of available Q Menu functions on Page 35 of the Instructions and available Fn button functions on Page 38. Highlight those you think you might prefer, decide priorities, make settings and run trials.

You may very well find that some function which you thought would require rapid access can better be left in the Main Menus and conversely something you thought could happily rest in the Main 
Menus would really be more useful on a quick access button.

For the record I have:

Fn1: Drive Mode.

Fn2: Focus Mode. 
Note that Focus Mode on this camera has been given a split presentation. The lever on the left side (as viewed by the operator) of the lens barrel has half the items namely AF/AF Macro/MF and the other half of the items namely [AFS/AFF/AFC] must go elsewhere,  in my case on Fn2.

This seems a strange arrangement to me. Why not put them all on the lever or all on a button ?
Fn3: Quality (JPG/RAW).

Quick Menu

Go to the Custom Menu, Screen 8/9 [Q MENU] and set [CUSTOM].
Pages 34-37 of the Operating Instructions explain how to set and use Custom Q Menu items.

You can allocate up to 15 items to the Q Menu but only 5 can be viewed at any time on the item bar. 
If there are more items, horizontal scrolling is required.  I find that if I have any more than 5 items I forget what’s there because I cannot see the hidden items on the first screen.

For the record I have 4 items on the Q Menu

* Silent Mode  (never used yet as the camera is so quiet even with the mechanical shutter).

* AF Mode

* Stabiliser

* White Balance

Setting Up the LX100 Part 1 Basic Decisions


LX100


The Lumix LX100  is an interesting camera which attempts to pack most of the features of a fully specified Interchangeable Lens Camera (ILC) into a compact form. 

The designers opted for an Aperture Ring + Shutter Speed Dial type of control system which has implications for setting up and using the camera.  

There is no Exposure Mode Dial and no Main Control Dial on top of the camera.

Modes and features usually found on an Exposure Mode Dial must be reached by other means.

This little series of four posts on setting up the LX100 is intended to be informative not prescriptive. I will describe some of the options available, discuss the advantages and disadvantages of each, as I see them, then describe my practice with reasons.

Users with different priorities will come to different conclusions about preferred settings and ways of operating the camera.

Lens Protection 
The LX100 lens is a high tech item with multiple aspheric elements. I imagine it would be very expensive to replace so I would not want to damage the front element.

Many smaller compact cameras have a built in multi blade type lens cap which operates automatically. The LX100 takes a different approach mainly I suspect because the lens is too large for the built in style cap.

The options are basically either the Panasonic LFAC1 petal type cap or the standard clip on lens cap supplied with the camera with or without a protect filter.

I have not tried the LFAC1 but I suspect it may not fit over a protect filter threaded onto the front of the lens. Also I am reading reports on user forums that the petals of the LFAC1 may not be very durable.

My approach is to fit a screw in 43mm B+W XS Pro 007 Clear MRC Nano filter and use the standard clip on lens cap. Any other slimline protect filter would do but I recommend a top of the line version for best performance particularly as there is no lens hood supplied nor does there appear to be any obvious means of fitting an aftermarket one.

This means I have to remove the filter and put it somewhere every time I take the camera out of its bag.

Carry Bag
There has been much discussion of this topic on user forums from owners seeking the perfect carry solution.

The LX100 has twice the box volume (width x height x depth) of the Sony RX100Mk3. This means the LX100 will not fit into most pockets so it needs a carry bag of some kind.

Some users have explored options for the smallest bag or pouch into which the camera will fit. Others including me have been more inclined to find a somewhat larger bag which allows the camera to be easily moved in and out and which can accommodate spare batteries, SD cards and maybe the (supplied) accessory flash unit.

There are also those who expect the carry pouch to be worn on a belt at the waist. Others prefer an over the shoulder style.

I am currently using a Think Tank Mirrorless Mover 5. This is slightly larger than required but provides a separate compartment for two spare batteries, a place for plenty of SD cards and the option of belt or shoulder carry style. The flap has a magnetic catch so the zip can be left open when out and about with the camera, allowing quick access.

I use the bag over the shoulder as I find it rather too bulky for the waist.  Also the belt strap is sewn in so to disengage the bag the belt must be substantially removed from one’s trousers.

I have also used the Lowe Pro Dashpoint 30 which is the same size as the TTMM5 but lacks the pouch for the batteries.

Others have reported that the Hama Odessa 90 is suitable.

Batteries

At least one spare [BLG-10 PP or BLG-10 E] battery is desirable for a day out with the LX100. I carry two but have thus far never had to use both.

Stills or video

I do not do video so I have no advice to offer about setting up for video. There are websites which concentrate on video however and the LX100 Operating Instructions have comprehensive information about video options.

Control Module Functions

Readers familiar with the typical Panasonic user interface and menu system will have no trouble setting up the LX100. But newcomers to the Panasonic way might find the process initially rather daunting as there are so many options available.

I hope the remainder of this post and the next three posts will be of assistance.

Direct Focus Area

Now we come to a critical decision which determines how the camera works and what is possible and/or necessary  through the rest of the setup process.

The LX100 like other cameras which use contrast detect AF directly on the imaging sensor can place the AF box anywhere on the frame and select any AF box size in 15 steps from very small to very large.

The LX100 like other recent Panasonic high end cameras can also set custom shaped AF areas. I suspect these are a techno-frolic by the designers, included because they can rather than because anybody said please can we have strange shaped AF areas.

For now let us just stay with [1 Area] Autofocus Mode which I have found to be the most useful and which I use 99% of the time.

Oh, yes while on that subject the default option for AF Area is [49 Area]. I strongly recommend against this option.  This has the camera decide where to focus which may not be where you want it to focus at all. The lens has a wide aperture with shallow depth of focus at the smallest f Stops, so this really matters.

There are three approaches to changing the position and size of the AF Area (AF Box).

Method 1. The default which you will find when first using the camera, works as follows:

* Step 1, Press the left cursor button [AF Mode] on the Cursor button/Control Dial module on the back of the camera. This enters AF Mode.

* Step 2, Press the Down cursor button to enter [AF Area] function. The AF box turns yellow with four yellow bounding arrows.

* Step 3, Press any cursor button(s)  to move the AF box around the frame.

* Step 4, Rotate the Control Dial to make the AF box smaller or larger.

* Step 5, Press the Disp button (while the AF box is yellow with bounding arrows)

Once, to recenter the AF box,

Twice to reset AF box size to default which is size 5/15.

The advantage of this default system is that you retain ISO, WB,  Drive Mode and AF Mode on the cursor keys.

The disadvantage is that you do not have direct access to moving the AF box. You must do a double press, using two different keys to get into the AF Area function. This is slow and a disruption to the capture workflow when you want to move that AF box quickly onto a specific part of the subject.

Method 2. Assign [Focus Area Set] to a Function Button.  Go to the Custom Menu Screen 7/9 then to [Fn Button Set]. Follow the prompts.  The only Function button adjacent to the Cursor buttons/Control Dial module is Fn 1, so that is the obvious one to use.

This works as follows:

* Step 1, Press the Fn 1 button. The AF box goes yellow with bounding arrows.

* The rest is as for Steps 3, 4 and 5 above.

The advantages of this system are that the default functions of the cursor buttons are maintained and access to moving the AF box is one step faster than the default approach.

The disadvantage is that it is not as fast as the next method and Fn 1 is unavailable for other functions.  

The opportunity cost of assigning any function to a button is that you cannot assign any other function.

Method 3. Set [Direct Focus Area] ON at Screen 3/9 of the Custom Menu.

* With Direct Focus Area the AF box changes to yellow with bounding arrows and moves immediately when any cursor button is pressed.

This is the quickest way to change AF box position and size.

The disadvantage is that access points must be found for ISO, WB, Drive Mode and AF Mode.

Which is best ?

One of the advantages of a highly configurable camera like the LX100 is that you can virtually design the way the camera operates to individual preference. The challenge is that such choices must be made from a dense multitude of options.

For the owner without previous experience using an advanced Panasonic Lumix camera, I would suggest starting with the default settings then experimenting from there. 

Some users,  perhaps with previous experience of  DSLRs say they routinely use the focus (with the center AF area) and recompose technique for off center subjects. Presumably these users have become accustomed to that technique, which I also used with SLR then DSLR cameras.

With the new mirrorless cameras the AF position and size can be changed so quickly and the operation of off center AF is so effective that I no longer use the focus and recompose technique at all.  

My practice is to set Direct Focus Area ON.

I have ISO on the Lens Control Ring,  White Balance and Autofocus Mode in the Q menu and Drive 

Mode on the Fn1 button.

I find this very logical. I want to move the AF box in Capture Phase, as I am in the process of taking pictures so I set that up for the fastest possible access with the least possible actions.

I may want to change ISO in Capture phase so that is on a quick access module.

I infrequently need to change Autofocus Mode so that is appropriately allocated to the Q menu.

I more often want to change Drive Mode so that is on a  Fn Button which is more quickly accessed than items in the Q menu.

Lens Control Ring

The lens control ring is smooth, not clicky. User assignable functions, Custom Menu, Screen 8/9 are:

* [DEFLT Normal], which on my camera appears to be exactly the same as Step Zoom

* [Smooth Zoom]

* [Step Zoom]

* [ISO Sensitivity]

* [WB White Balance]

* [Filter select]

* [OFF Not Set]

I have found there is an ergonomic issue with the lens control ring. It is easily bumped accidentally when changing aperture or aspect ratio or focus mode. The ring turns easily and gives no feedback in the form of clicks to indicate it has been turned.

Several of the functions assignable to the lens ring don’t make a lot of sense to me.

Zoom is more easily controlled with the zoom lever in front of the shutter button.

I won’t put white balance there as the ring is so easily bumped.

Filters already have a dedicated button in front of the Exposure Compensation dial.

That leaves [OFF] or [ISO Sensitivity].

I have [ISO Sensitivity] there at the moment but am seriously considering the prospect of disabling this ring as I quite often notice I have bumped the ISO setting off Auto which is what I use for the majority of my photos.  I could put ISO on the Q Menu.   Or a Fn button, but then I would have to move something off  that Fn button onto the Q Menu, probably Drive Mode.

You see how this works. It’s a game of consequences and opportunity costs.

You have to decide what function to allocate to each control module and every decision sets off a little chain reaction.

Good luck.

Next up, Q Menu and  buttons
