YetiYeti: Which weapon systems will it be able to pack?
The camera is it's weapon!!
There is more to lens than sharpness, allot more.
Biowizard: Thinking about "Full Frame" (linked to the outmoded concept of 35mm film), here's my take ...
The sensor I'd like to see in a "Pro" DSLR body is 43mm CIRCULAR one. This would capture the ENTIRE image circle of a standard full-frame 35mm lens, with the following benefits:
1) Capture 36x24mm landscape AND 24mmx36mm portrait images SIMULTANEOUSLY on a single file
2) Eliminate the need for a second grip, shutter release, etc., because the camera would NEVER need to be tilted sideways
3) Eliminate, once and for all, sloping horizons: because a FULL 36*24 or 24*36 "level" image could be obtained without cropping
4) Provide 30mm SQUARE format, or 34.5x26 / 26x34.5 4:3/3:4 aspect ratio images, using MORE pixels than the standard 35mm "full" frame
After all: when we use binoculars or a telescope, we are perfectly happy with a circular field of view, and never experience "sloping horizons", so why not for cameras too?
You heard it here first ...
[Ed. got two dimensions wrong!]
That camera would need a completely new mirrorbox with taller shutter and taller/longer mirror that would probably make trouble with flange back distance. And of course a new bigger pentaprism etc.
