Looking for Nauticam N85 Extension Ring 20 #36620. Preferably in EU as that would avoid customs hassles.

On the contrary, I was surprised to read in a thread that B+W NL5 could achieve that. Since I don't have one to try I was hoping that someone tested it and could share their opinion. Nauticam's recommended option is quite expensive. I would be interested to hear from somebody who actually used it (140mm optical) and could compare to 4.33" acrylic, before I even consider that option.

Olympus 12mm 2.0 seems like a great companion to the Panasonic 8mm FE (sharing the same Nauticam 4.33" port and being so tiny). I took some snorkelling snapshots with it and there are two issues that annoy me: #1 The edge softness. Wide open the edges are very soft. I found an old tread on Wetpixel with suggestion to use B+W 46mm NL5. Supposedly it gives sharp corners even wide open (the sample images from that thread are not available anymore). I could not get hold of the B+W 46mm NL5. I tried Hoya 46mm +4 instead. It helped but I'm not fully happy. Should I keep trying to get the NL5 instead? Would it work better? Is there anything else I could try (other than shooting it stopped down to f8)? #2 Lens flare Since I shot it at the surface and directly into the sun I got a lot of lens flare (as expected). It seems there is enough space between the dome port and the lens to fit some lens hood. Did anybody try that? Which lens hood fits the best?

I neglected diving and photography in the recent years. Trying to get back to it now...
