View Full Version : Removing process lens with screw access blocked by aperture ring
Very sorry for the banal question, but there must be a simple way to do this that I'm missing. I would like to remove the lenses below from the large board (some kind of reprographic camera board, I imagine), but access to the mounting screws is blocked by the aperture ring (see picture). How does one go about removing them? Thanks.
All the best,
Leo

Those lenses look like Konica Hexanon GR IIs. I just took out my 210/9 and looked at it. It is threaded at the rear. If your lenses are GR IIs they should unscrew from their flanges.

Thanks, Dan. They are GRIIs. I tried like the Dickens to unscrew them from front side and rear (at least on the larger one) but neither will budge. When you say unscrew, you mean simply by grabbing the lens and turning it, correct, not having to use a lens wrench to remove a ring for instance? I appreciate the help.

Exactly. I'd freeze the assembly, attack it gently with a strap wrench.
Ok, will try further. Thank you.

What does the other side look like...sure it is not locked with a ring on the other side?
