Most of these wishes also appear in the GX100 list.
+-1 and +-2 EV bracketing - Good for HDR photos and while the camera is capable to go +-2 EV exposure, why not in bracketing?
An option to shot DNG only without corresponding JPEG - It should make
the GX100 RAW writing 1-2sec faster (with currently the fastest card
Sandisk Extreme III or Panasonic SDHC class 6) or even faster in case
of GRD. No JPEG processing = less time required for writing RAW..simple
math;) There should definitely be a difference between storing just
single 14MB file and storing 14MB + processing and storing additional
3,5MB JPEG? Many shooters (especially GRD users) would gladly pay the
price of lost RAW preview (which is not RAW preview at all) if it would
mean faster RAW writing. Not to mention that there already is a small
thumbnail stored in each RAW. Sure, it's small, but why not use it for
rough preview?
1:1 RAW format - There already is an option for 3:2 RAW so why not 1:1?
Possible slowdown because of RAW processing?? 3:2 saves slower than the
original 4:3 RAW so maybe the 1:1 would require even longer time?
BW jpeg customization (GX100: contrast/sharpness + GX100/GRD: B&W
color filters) - Definitely! Great for all "pure" B&W shooters.
Focus Lock - Not just by half pressed shutter button, but the same
(similar) way as AF Lock. Even Canon Ixus compacts have this feature
and it's very useful! No need to press an hold the shutter button all
the time! [R3/4/5/6 can do this focus lock by achieving auto focus then switching to manual Focus... Guy]
Power ON after Auto Power OFF using just the shutter button - that's sounds reasonable.
Better, more granular, battery reporting. - more precise battery status
would be really welcome. This is something I really love on Sony
cameras.
Interval shooting start from 1 or 2 secs - Manual continuous shooting
allows to take 1.6 frames/secs so why not to allow Interval shooting
from 1-2 secs? Starting it from 5 secs is too limiting.
NO EXPOSURE SIMULATION IN M-MODE.
I use mainly the M-Mode with spot metering. The exposure indicator
works very good but I hate the software for simulating the exposure in
the display in this particular mode. This is done for example by
darkening live preview when a underexposure-setting is set. Especially
when working with an external flash unit, this can result in a totally
black preview if you stop down the lens, set a small ISO number and a
fast exposure time (which might work well with the flash, but you can't
see anything of the scene in the preview). I would like to have a clear
preview of my scene, no matter which exposure parameters I set in the
M-Mode.
MORE DIFFERENCE BETWEEN THE P-MODE AND THE GREEN-CAMERA-MODE.
As far as I figured out, there is no difference between this both modes
if you aim and shoot. The only difference is the aperture/time shifting
ability in the P-Mode. I would like to have the green-camera-mode for
shots where I don't have the time to set new iso settings for example.
So in the green-camera-mode, ISO should always be "auto", the metering
mode should always be "multi" and so the AF, no matter what ISO,
metering and AF is set in the other modes. This would result in an
"idiot-proof" mode for spontaneous snap-shots.
BIGGER EXPOSURE INDICATOR WITH EV SCALE IN THE M-MODE.
If you use the display without any parameters displaying, the
parameters only show up as long as you change them. I like this very
much because this way I can see the parameters when I need them and can
compose the picture without having the numbers and symbols on the
display. Anyway I would like to have a detailed exposure indicator (the
bar) with an EV scale.
last but not least:
