My question (and I understand that the issues of professionals are not mine):
I am an old D-300 shooter and probably more of the target of Nikon for underwater users of this camera (if they care about underwater photographers at all).
The plusses:
1-More megapixels
2-Like the 1.3 crop but really why not just crop?
3-May actually be Ok taking video with one touch white balance
4-Better all round sensor
Don't care
1-Build quality. I don't use my underwater camera out of the housing
2-Dx vs FX is a tradeoff. I am mostly a macro shooter but would like the flexibility of a FX/DX combo
Negatives
1-I have a prefectly good Seatool housing for my D-300 and 2 perfectly good D-300 cameras.
So, in reality, only diving 15-18 diving days a year 30-45 dives, how much better pictures will I really get?
