chrispak1962 0 Posted December 4, 2010 Hello, Are there photographers who use the 8-16 mm Sigma underwater and can you show me some photos taken with that lens and tell me what kind of dome you use? Share this post Link to post Share on other sites
Timmoranuk 10 Posted December 4, 2010 Yup, I shoot the Sigma with a 200mm Zen and 40mm extension. Corner sharpness with the 200mm dome is OK at f/8 or smaller though you could probably squeeze an extra stop or two with a larger dome. I'm looking forward to shooting wrecks with it and retaining some straight lines in the images. Also, when I'm shooting w/a with CJ we can swap around the rectilinear (8-16mm) with the fisheye (10-17mm) glass and get different perspectives of the same subjects. It just adds a little more interest but I wouldn't be without my Tokina... Share this post Link to post Share on other sites
PeteAtkinson 53 Posted December 4, 2010 I use the 8-16 with the Seacam Superdome. I need f11 to get acceptable corners. I also tried the Seacam 6" dome but couldn't get better results. I didn't have exactly the right extension, but I don't think that was the issue. I like the rectilinear look better than the 10-17 with many subjects. If anyone has managed great corners at f5.6 with this lens, I'd love to hear what dome and extension. Share this post Link to post Share on other sites

Hi, here are some reviews of the lens: http://www.uwphotographyguide.com/sigma-8-16mm-review http://www.kenrockwell.com/sigma/8-16mm.htm Here's one review in combination with Zen 230mm dome and 60 mm extension, should give acceptable results from 7.1 though personally I wouldn't go below 8 if I don't have to. I'm going to buy the lens for the d7000 in a Subal housing with a 230mm dome that I already have. Very nice, coated inside and outside (industries first): http://nauticamusa.com/?p=778 Share this post Link to post Share on other sites
