JSatoshi 0 Posted June 29, 2017 I do a lot of in-stream photography and I would like to use a compact 6" dome on my Ikelite housing rather than the giant 8" dome. This is for an A7RII and primarily a 28mm F/2 with fisheye converter. I was wondering if anyone has experience with this setup or if someone knows if it's possible or not. Ikelite's port chart makes no reference to the 6-inch dome other than that the 15mm Sigma causes vignetting. I tried to contact Ikelite with no success. I also got in touch with Backscatter.com but they didn't seem to have any idea either. Thanks. Thought I'd check in with folks here before I fork money over to try it out.
