I like the D700 but want a change for two reasons. First is more MP and second is shutter noise. Its for all-round use and I need a good sized viewfinder for ease of use with eye glasses. Something a bit lighter would not go amiss (but not essential). I'd be buying second hand. D750 seems the obvious choice, but is there anything else I should consider?
I agree, loved my D750 apart from the noise, even in quiet mode for bird photography, one shot and off they would go. The D810 is a lot quieter compared to the three D750's I have owned.
