Does the pro version have 2 internal flip levers for the color filter and macro diopter? I searched for a pro version for sony, but couldn't find one and wanted that feature.
What I've found really helps the color is manually setting the white balance with a grey slate. The housing allows you to do this with one button press if you set it up.
As I recall, there is only one internal flip lever - I use a color filter on that one, and use a SAGA flip adapter for my external wet lens (Subsea diopter for macro).
Yes, I also do manual WB, both with my current Canon camcorder, and previously with my old Sony. The Sony always ended up with a greenish cast that I just couldn't seem to get rid of, even with post-processing, so I was never really happy with the color from that camera. I still need to do some color correction with the Canon, but the final version is more pleasing to me. Thanks for the help, though.
