Nikon D850 vs Sony a7R III Underwater Camera Comparison – Full Frame Showdown

Thanks! Share it with your friends!

Close

Over the last few months, we’ve had a chance to test two of the world’s most popular professional camera bodies, the Sony a7R III and the Nikon D850, to gauge their strengths and weaknesses shooting underwater. Backscatter CEO Jim Decker and media producer Robin Dodd sat down to discuss camera features, lenses, and a few of the drawbacks of each. Check out the video below or scroll further and read on.

We’re trying out a bit of a new format with this video. It’s a long format but the discussion is filled with the kinds of details that us underwater photographers need to know. We hope you enjoy and please leave us some feedback letting us know whether you’d like to see more content like this!

@backscatter I’m amazed with that purple slider on the Sony – can you please confirm which purple slider you’re using? I have this issue on occasion and have no idea how to correct/ what slider you’re using?

John Park says:

Using a third party lens with a metabones adapter will have drastic effects on focusing speed and keeper rate, hence your issues with the a7Riii. Put some native mount (Sony, Sigma, Samyang etc) glass on there and it will focus faster and better than the Nikon.

That was a very good review, so detailed and with such interesting results from your subsea experience, rather an unusual and exciting review I think

Denver Maddux says:

Fisheye lenses don’t make a camera system viable or non-viable. Marking down Sony because of that is fairly poor reviewing. Also the fact that you didn’t compare the cameras using native lenses, like a very popular 16-35mm selection for both systems, is unfortunate. The housing size matters for travellers. Every kg counts. Battery life? Ease of access in the housing? Button layout? Menus? Thanks for the amount of detail provided, though.
