A very nice Ercona II with a 3.5/105 Tessar showed up on my doorstep today
. The front of the lens isn't threaded for a filter. The diameter of the knurled outer rim (used for focusing) is 40mm; there's a thin recessed slit inside this with another edge that's 37mm across. I guess either a 37mm or 40mm push-on Series VI adapter would be appropriate. Any other ideas for using a filter with this camera with fewer than 3 hands?
The tripod mounts are much bigger than 1/4-20 - are they 3/8-16, or some metric size? I don't have any 3/8-16 hardware or tripod mount reducing adapters so I can't answer this question for myself.
Thanks for any insights.
