Re: Why are cameras so big?

Full frame translates to high end.
With High end, you need to have a big viewfinder that's really bright.
To do this you need a big pentaprism - not mirrors.
This is a big chunk of glass.

next, with high end, users expect an alloy shell and some kind of weatherproofing.

If you add this together, the pentaprism is bulky - sure you can make the rest smaller (except for batteries and memory card connectors) but if you balance out the rest of the camera it is actually quite big.

So the engineers have a fair bit of space to place the various controls around the camera and decide to add a bit more bulk to give you grips, dials, screens etc.

Sure, you could have an evf, lose the pentaprism, controls, large high resolution screen etc. but high end users wouldn't buy this (or so they determine) - or it's a new bracket of product on the market which translates to much higher marketing costs to gain acceptance. - thus not really worth it as even with the bigger sensor, you're losing review points for the evf (not to everyone's taste), brightness and flexibility.
Right now, you have the D7000 which is superb and the D800 coming along soon...
