I got into wedding photography a couple years back and i'm excited to buy a full-frame Nikon when the D4 and D800 are released. The question is, which one?
Pretend for now that the D4 and the D800 have the *same price*, because I want to understand why one is better than the other. Then we can talk budget later...
The weddings i've shot so far, I borrowed a D700 and loved it. Its low-light capabilities were sufficient for me, and for the other types of photography I do too. So that begs the first question: do you think the D800 will be at least as good as the D700 in terms of high-ISO performance? To explain how I think about this question: shooting at ISO 3200, will the noise and detail retention on the D800 be as good as the D700?
The second question: do you think the slow FPS of the D800 (rumored to be 4fps) is by itself a reason why this camera won't be good enough for weddings? If you answer this question, please also tell me how long you've been shooting weddings for.
Thanks for your help.
