Has anyone used either of these two domes with fisheye lenses on a full frame or APS-C camera? How was the performance and image quality if so?
My understanding is that both these domes are designed for wide angle lenses rather than fisheyes, so the angle of curvature is different -- they're slices from much wider diameter domes. How would this impact their use with fisheye lenses? Am I going to get better image quality with a smaller fully-circular dome like the Nauticam 140mm dome or the Zen 100mm dome?
Use case -- Canon 8-15mm lens w/ or w/o 1.4x teleconverter an a Sony A7RII camera. Potentially the Tokina 10-17 with a Nikon D500 in the future. I'm trying to find a dome that's a good balance in terms of image quality, price and size for travel.
I'm currently using the Nauticam 8.5" dome and I'm happy with the image quality at F8 or narrower (usually shoot around F11). But the size of the dome is a little inconvenient for travel, not to mention that it makes the camera a little too positive at the front (have to counteract by strapping a 1kg weight on a weight belt around the dome port extension). One further advantage I see to the 170mm/180mm domes vs a 140mm or 100mm dome is that they would make shooting over-unders a bit easier.
