First series RB lens, pre-C. Glass is good. Body is good. Has no hood. Has one loose aperture blade. See pix. Aperture will stop down, and the loose blade is mostly out of the way, but the aperture opens a little sluggishly and needs a little fiddling to open it up if you stop it down. This happened in shipping, so I think the repair will be fairly simple. Probably just need to hook that one blade back onto its pin. I shoot it wide open on negative film with a half stop added just to cover that sagging blade, and get sharp pictures with a lovely non-coated quality.
Asking $40 or best offer, plus shipping that is probably about $10.
P.S. Image files names say "RZ," but this is an RB lens.
