You can't sync reliably past 1/180th of a sec with your camera. It is funny how it bounces around and works sometimes though.

Proscriptive? Heck, in my old age, I've been going back to primes. Fast, cheap and sharp. Zoom with your fins!


Not to get off the OP's questions, but I'm dying to try the Nikon 28 f/1.8 on a D800 there...


Echo Tim's comments about murkiness at times in Socorros... viz can be up and down, as wind blows volcanic ash off the islands into the water, or surge stirs up the bottom. Of course, that's when you see the largest schools of hammerheads...


Whatever lens you take, you'll have a great time!

You might see if in LR you can remove some of the aberrations with a couple of clicks...

Looks like you're shooting at too fast a shutter speed. On your camera I think you cannot sync faster than 1/180th of a sec. Post some of the camera settings from the exif of the photos.


I did notice this same issue while recently shooting a Sony a7, which is supposed to sync to 1/320, but the issue cropped up at time at 1/250th using rear cutain sync. You might have to use front curtain sync to get the fastest sync speeds? Not sure...


This issue should be able to be duplicated easily on dry land, just try some of your fastest shutter speeds with an external strobe and see.
