I've been using and RX100M2 in a Nauticam housing for a couple of years, and am happy with it in general. But the inability to UW white balance has forced me to use a color correction filter on my WA wet lens, and it's a pain to pop it on and off when I want to switch from ambient light video to flash photos and back. I was intrigued to learn about the LX10's ability to easily custom WB at depth, (and was VERY unhappy when Sony decided to firmware update this feature into every RX100 model except mine and the M1), so I have started to research the LX10 as another potential lightweight rig.
I've read that the LX10 won't effectively use auto ISO when shooting video. So if I understand correctly, if I wanted to keep shutter speed (and lighting) consistent in a video sequence, I'm forced to use shutter-priority and watch the DOF drift around with any changes in lighting due to aperture changing rather than ISO. Is this right? Ugh.
Also, I use an Inon UWL-100 28AD wide angle wet lens with the Nauticam housing. This lens has the AD bayonet mount, and I'm able to use it with the housing's M67 filter threads via a cheap M67-28AD adapter ring. It works REALLY slick being able to quickly change lenses underwater, and it shoots without vignetting. Can anyone tell me if I would be able to use this same wet lens with the Nauticam LX10 housing with little vignetting? Does the camera's lens come physically close enough to the port glass?
