Does anyone know of a reference for various INTERNAL DIAMETER sizes for different manufacturers ports? eg Ikelite can't handle the 14-24 Nikkor nor the 16-35 II Canon because those lenses' diameters are too big (but they will fit in the Aquatica). I want to use a lens 103mm across, which I think is too big for Aquatica. Would it fit inside a Subal? Seacam? Nauticam?
Thanks, DEC
103mm is too big for Seacam.
It's a no-go for Ikelite as well. The Ike ports are ~85mm ID without the zoom ring and ~80mm with the zoom ring.
Same for us, we have a +/- 99mm opening Depending on port
