- Dynamic range! The D7000 offers 13.9 EV of dynamic range (only beaten by the Pentax K-5 with 14.1 EV at the moment - in fact, these two cameras with their APS-C sensors leave ALL the other cameras behind, dynamic-range wise. Including medium format and the D3x!). And I've always cared a lot more about dynamic range than anything else - it was the reason why I went with the Fuji S5pro (at the time when I reached some limitations of my first DSLR, the D70s.) I just don't like fiddling around with ND grad filters, I prefer to expose to the right without blowing the highlights and then work on the shadows in post.
- Weight and size of the body. The D700 fits my hand nicely, I really like the handling - but the weight of that thing, combined with the glass... man, it certainly sums up.
- Money. Yes, it's that simple. Full frame glass simply costs a lot more money than DX glass. My current lens setup is nice, but to be really happy I'll need two more lenses: the 16-35/4 (which, unlike my Sigma 12-24 can take filters, and has VR) and the 24-120/4 (which has VR, meant to replace my Tamron 24-135 which is terrible in backlight situations) - and both of them together will set me back over $2k. Ouch! It's not that I really need these lenses right now, but on the other hand, Shuwen and I already have almost the exact same lens setup for DX! (and a couple of lenses are dupes at the moment...)
- More Tele! Darn, I can really tell how much I miss that crop factor when I mount my 70-300mm lens on the D700.
- 100% viewfinder. You'd really think that this is not really important, but damn I can tell you it's just plain annoying to compose a scene and then find that a stupid twig or a persons head or something is sticking into the frame. I don't like throwing away resolution in post to remove elements that I did not see in the viewfinder.
What will I lose?
- As it seems, just one stop of usable ISO. This wouldn't hurt me much - my always-on lens is the Tamron 24-135 at the moment and it's not stabilized. My photography doesn't require a fast shutter and I benefit a lot more from stabilized lenses (VR) than I do from high ISO.
- A separate AF-ON button on the body. I never use the AE-L button on my D700, so I might just as well reconfigure the AE-L button on the D7000 to be my AF-ON, just like I did on my old old D70s.
- The charming lens performance on the 12mpx FX sensor of the D700 with it's huge pixels. The D7000 crams 16mpx of resolution on a sensor thats less than half the size. To fully utilize it, you need to both work more carefully and have good glass. This one indeed keeps me thinking.
- The big viewfinder of a full frame camera. Oh yes. I know this would hurt.
- The fast 35mm lens. I'll need something like a fast 24mm prime to get the charming 35/85mm combination on DX (24/50mm sounds reasonable.)
- Memory cards, spare batteries, and accessories like the cable release.
If anyone of you has any thoughts on this, please share them with me. Just leave a comment. Thanks!
