I have now used the A6300 for several dives with the 90mm macro and the biggest problem to me still remains battery life. The 90mm has heavy glass that needs to move over a longer distance than with the kit and wide lenses, this results in greater battery drain. I was getting three dives with the Zeiss 12mm and only one or into the second dive with the 90mm about 150-160 images shooting in the 1:3 to 1:1 range. I did not have a manual gear for the lens and I am sure battery life would improve if focused manually. I was using the 0.5 meter to 1:1 setting on the lens and focusing on the LCD using the Ikelite housing. I get a bit better battery life with the A7R II more in the 200 image range and using the EVF. This camera has excellent image quality but Sony needs to address the battery life issue in future models even if the body needs to be a bit bigger.
