OK so if your really asking what I would really like to see in the new upgrade, then here goes:-
1)
Changing the Wifi connection so that the camera wifi can be initiated as a wireless hotspot, allowing any computer or device to connect to it with appropiate password. If the WIFI card in the camera can support the AP function then this would just make logical sense. I have never been able to connect the camera to my macbook via external router, but also when I am on location shooting I never really have access to an external router, only my camera and laptop.
If a device could connect to the camera and see the card as a storage device, then it would be fairly easy for individuals to write there own scripts to move files to the computer, with the computer doing the processing work. (less overhead on the camera).
2)
Support for digital focal zoning - ie, on lenses like the 56mm it would be nice to see a relevant digital focus zone range, that changes with apeture.
3)
The ability to place the histogram full screen. It would be nice to have this on the back screen while still being able to look through the EVF without it.
4)
Additional customisation of functions - So for example, if I set a function button to face recognition, instead of getting the menu that says ON or OFF, the button could simply act as a switch, 1 press ON, 1 Press OFF.
5)
More control over manual focuing sensitivity - The ability to set this.
6)
The ability to edit the name of the Custom settings.
