Hi Guys - I just got a 180 from a less than honest eBayer :twisted: ... The shutter and lens needs some work. I've been able to get into the backside of the lens assy. to clean out the shutter but now I need into the front to look at the aperture mechanism ... How do I get in there? I've tried unscrewing the black "Tominon" ring with a rubber bung but it won't budge. Any ideas??
I'm stumped on this one

TIA
