I'd like to see USB or Wifi tethering for stills, with ability to control settings of camera and shutter from an app. Like Lightroom etc. That's just software.

HDR video like Red HDRx and Canon's Magic lantern (24fps = 48fps (regular exposure and X exposure)

Log profile

Not likely, but higher than 8 bit video. 10 bit would be fine

META DATA!!!! Even if it is a sidecar file why not record the camera's meta data when shooting video. Ever do a test of different f stops/picture profiles/shutter speeds. If you click a still during video recording I guess the meta data is in the jpg, but when you are shooting fast, you forget.

How about additional crop modes. Something less than the current 2.6x. Just enough to use C-mount lenses without vignetting. There must be a pixel ratio that is divisible without much loss of quality. Just one more would give 3 focal lengths to a single prime. Needs to be easy to cycle through them. Imagine you are out with the 20mm. You are filming something. Touch a function key and you at 1.5 crop or 30mm. tap the function key again and you are at 2.6x crop or 52mm. And you haven't changed a lens and you can be shooting at f1.7.

More for stills:

Timelapse intervalometer.

Single click multiframe bracketing for HDR (BURST)

Electronic shutter for timelapse (like G5)

SILENT MODE for stills

Focus peaking

How about lower ISOs like 50 and 100

+2 for anamorphic, better 4:3 video quality mode (something like 4:3 24p or even 60P) so you can use with various anamorphic lenses.

A time lapse mode, with more granular control of aperture and shutter. Even better if the aperture and shutter values could be ramped up and down slowly, over time

Let's formulate it like this:

• Timelapse animation feature.
• Mobile application must allow to set up to 1000 key frames, with defined time interval, zoom position, focus position, shutter and aperture values, ISO value. You must have ability to store this data or beam them other WiFi to camera.

Let's get camera spec and make proper calculations

4608x2592 = 11943936, as it is 12 bit raw * 12/8 = 17915904 bytes
make frame rate into account, * 24 = 429981696, this is about 430 mb /sec It is in the realm of fastest SSD drives, but remember that data to them are delivered using very fast RAM with wide dual channel bus and very fast CPUs.

Camera could't make proper resizing maintaining RAW.
I have very strong suspicion that LSI is just unable to do it at all, at any resolution or framerate.

@Tristan

Answer is simple. Camera follows AVCHD standard. :-)

So, to rephrase, you are for MP4 as main container. And make it not restricted by 4GB.

• Something like: make support for exFAT with sizes larger than 4GB. Make MP4 the default shooting format.

Ability to save stills sequence of 3840x2160 "S-Raw" .rw2 or .tif sequence Until sd card is full, at 24-25 frames per second

Can you be more detailed?

And make some calculations showing required SD controller spped and required SD card speed?

I also hope that you understand that LSI won't have enough resources to do raw compression?

Ability to save stills sequence of 3840x2160 "S-Raw" .rw2 or .tif sequence Until sd card is full, at 24-25 frames per second.

+1 for anamorphic options, and not just guidelines. Many people shoot 2X anamorphic, so a 4:3 video mode would be extremely useful to get 2.35:1.

Alternatively, 4:3 guidelines while shooting in 16:9 would also be a useful feature.

The option to actually desqueeze the footage in-cam would be amazing, especially if it was done in a way that horizontal resolution is not halved. (I have no idea if this is even doable, perhaps VK could weigh in?)

Selectable external audio input level: mic level, and line level (by-passing the internal preamp)

This is hardware stuff. Not for this list.

Deletion of “Shoot without Lens” which is both confusing and incorrect (you do no shoot without a lens!) and use auto detect instead.

Can be changed just to warning upon power up, if lens without chip is used, it must ask if everything ok. And if you answer yes - it never ask until next lens change.

All buttons should be programmable as Fn buttons, with all functions, not just a limited choice. I for instance don't really need the Q.MENUE button but would much rather have the opportunity to use it for the highlight function in order to check for overexposure when needed. But I don't want that function on permanently as it is quite disturbing.

I also want focus peaking, via Fn or dedicated button. (I know this is not about hardware but it would be a good idea if Panasonic chose to give us more Fn buttons. Move the playback button to the left of the viewfinder, next to the LCD/VF button, move the AF/AE lock button to where the playback button was, put an additional Fn button where the Lock button was.)

One firmware thing: When choosing EX Tele in video mode I want the video EX Tele mode to appear as default. Same goes for Photo EX Tele mode. The GH2's default is Photo EX Tele in video mode and Video EX Tele in photo mode which is pretty stupid.

defineable parameters for live-streaming via wifi signal from the camera - adjustable bitrate for streaming to live web-serving, or to tablets (Android or Apple) for ultra low latency client viewing or remote control.

File prefix naming for clips either on a per-card basis, or resettable on user demand. (e.g. a 4-6 character prefix that could indicate the scene name).

One of the most-wanted feature is the custom picture profile selection on GHx cameras... That would be good to see in GH3...

I'll reformulate it as follows:

• Application for PC and Mac allowing to define raw processing rules
• Ability to upload custom created rules via WiFi direct
