I’ve recently traded in my old Sony a77 for an a6000 and I must say, I’m impressed. It’s tiny, inexpensive, performs very well for both photos and video, and is cheap to put underwater.
It’s also a great platform for adapting vintage glass! The photograph below was taken with the Minolta 70-210mm f/4 “beercan” lens on the first real day I took the new camera out for a shoot.
I can’t wait to get the a6000 underwater and see how it performs in that environment!
