Reef Photo and I are trying to figure out if a Sigma 10-20mm lens will fit into the SeaTool dome. While I'll be using the 10-17FE for most WA work, I'm getting a 10-20 or 10-22 for topside, and might as well have one which can work u/w for those times, like wrecks, when rectilinear is preferred to FE.
We know the 10-22 requires boring out a bit of the collar. How about the 10-20? Fit without modifications? If someone here is using this configuration, will save Reef the time of tracking down a 10-20 to test.
