I have a D7000, before that, a D70s. Great cameras, but I hate the finders and dealing with crop factors, especially in the wide end of the focal length spectrum. I shoot mostly macro and portraits, and I find those sweet short teles don't look so short and the wides just don't cut it. I tried MF lenses, but the finder stinks and Live View never seemed to get it done for me. Sure, Live View works well for macro, but I don't care for it doing portraits. I like my eye to the finder.
Soooo, that leaves me with one option. Sell my D7K, plus the 3 DX lenses I have. Fortunately I have FX lenses where it counts for what I do. I can make pretty much what a used D700 goes for from the sale of my DX gear.
If you were in my shoes, would you make the move to FX? This is not a spur of the moment idea for me. Been thinking of doing this a long time. With the new cameras coming out, it seems like the perfect time to snatch one up.
