My llst (I already sent these to Nikon but another vote in favor might help)
- Vertical button has 3 option. On, Off and position dependent. When the camera is horizontal the switch is disabled. When vertical, it is enabled (say w/in 20 degrees of vertical)
- Pressure sensitive shutter button. When pressed hard, there will be a click which will engage high speed mode. High speed frame rate will remain on as long as the shutter is pressed hard (or perhaps while the camera is shooting). Camera will return to normal shooting mode (single shot or low speed frame rate) after the shutter button is released
- Turning the camera on and off for a short time (say less than 5 seconds) would reset some user defined functions (such as bracketing, exposure compensation, frame rate, meter and focusing mode, …). If turned off for a longer period time, additional user defined sets could be returned to the default values (banks, metering modes, …)
- Raw capturing at least 30 FPS (in full frame mode), as well as precapture of raw images.
- Metering mode that sets the exposure (Shutter speed, aperture, ISO depending upon the mode) to allow X% of the image to be clipped (% to be clipped can be set by the user as well as if the clipping is measured by color channel or luminosity).
