....For a fleeting moment I thought maybe I should take a close look at the D500. But then sanity kicked in....
Do it! You know you want to!
FX or DX, both are capable of rendering high quality images suitable for publication and wall prints. Any camera body has its pro and cons.
Personally for me it ends up being a case of diminishing returns to consider moving to FX from DX. Factoring in body, lens and housing taking
a FX camera underwater is a considerably more expensive proposition. Then of course is the increase in weight and volume. Also FX just about
makes using a large diameter dome a necessity and I love compact domes.
Of course if your pockets are deep its all academic.
As I'm on a hiatus from diving the new D500 has huge appeal. Will definitely be picking one up to shoot the birdies with. If I don't house it I'm sure
I'd be just as happy plonking my current D7100 in the water.
Yes FX is a superior format in many ways, as far as resolution and added capabilities/functions in the bodies on offer. But UW aren't many of those
advantages reduced and as pointed out previously it is very hard to pick up any increase in IQ with the naked eye.
