Has anyone shooting Full Frame shot 35mm underwater? I've been shooting 14mm underwater, and find that for a lot of subjects, it's just too darn wide. I know closer is better, and for that reason, wider is usually better; however, sometimes you just can't get close enough to some subjects. I was thinking about getting a Sigma 35mm ART lens anyway, but was wondering if anyone has had any experience shooting 35mm underwater. The other option I was looking at was 24mm. I use a Sea & Sea housing with a Zen Port glass dome, and I believe it will work with either the 35mm or 24mm lenses just fine. Any thoughts, comments?
