I have these problems both with the additional W/A lens as well as without it.
The W/A lens is a Sakar 0.45x 58 mm lens. So when using that, there are no camera silver parts visible. I have attached 2 photos of the w/a lens and as you can see, many rings are created by it internally, so nothing can be matted or painted black there. Could other w/a lenses be better? Or do they also have similar appearance which would relfect on the dome? What do the Sony and Keno W/A lenses look like from the front?
Without the additional lens, the rings (just somewhat different) appear. In that case I could paint some part of the camera silver rings black, just I am afraid that even in that case the camera lens itself might relfect from the dome. Without the w/a lens the camera is also at least 2/3 inces from the dome port internal surface, which I assume makes things even worse.
