Why a camera can not be small AND have a deep grip

6 Aug

I keep seeing people clamouring for a system camera with a low depth, low width and a deep grip – see for example this recent thread on a popular forum. The hope, it seems, is that a mirrorless camera can provide this. Unfortunately, that’s not so. Mirrorless camera systems are designed on the idea that with the registration distance being shorter (because there need not be a space for the mirror), lenses can also be built to a more compact design. This comes with a number of challenges, one of which is illustrated below:

There physically isn’t space for a deeper grip, because it will not leave enough space for the fingers to fit between the lens and camera. I’d wager that for the same reason, it would be very difficult to design a similarly short 16-35mm f/2.8 lens, and equally this may be the reason why the A7 system’s 70-200mm lens is an f/4 rather than f/2.8. You quite simply have a problem if you want to fit a fat short wide aperture lens close to the camera body and have a deep grip for chubby man-fingers (no offence intended).

So there. I hope that covers that. Next time, I think I’ll include an X-ray of the fingers. 🙂
