Thanks, Bill; any tips on how to do that? Turn this, push that, etc? The piece didn't come with any instructions.
I just found (find) that I have to "fiddle" with it to get it to work properly - I am away for a few days - but when I get back I'll take an image of the adapter fitted onto the FD lens to show where the lever should be - just mess around with the position of small tab and lever - it is a good fit once it's on - but it seems not to fit when you first try - if you get my meaning
When I first got the adapter - and fitted it - I got no f stops - it took me a while to figure it out - if I am making myself clear
It is strange as all my other Chinese adapters, Konica, Nikon, Leica etc., fit with no problems - but the Canon FD mount seems to be a little more complicated in the way that it works
i own the 70 - 210 f 2.8 -4 vivitar series 1 purchased for my nikon 8008s its an af lens but
thankfully has an aperture ring , it does 1:2.5 macro at the long end , and its quite the optic for its time
