UliWer Posted December 17, 2022 Share #1 Posted December 17, 2022 Advertisement (gone after registration) Before I bought my first Leica I had a Minolta X 700 and was very fond of the W-Rokkor 1:2.8/24mm. Every time I looked on old photos taken with this lens I regretted having sold it. Today I found a very good copy and a Leitz 22233 adapter (originally made to use the Minolta lenses with the Leicina). Though I think there is a problem adapting this lens. The 22233 adapter does its job, but the lens has a small part which pressures on the adapter's flange. It can be seen here in the photo between the red dot and the "24" mark: Welcome, dear visitor!

This little part is so tight on the adapter's flange that you almost cannot change f-stops. It works with a lot of force though this isn't convenient. I don't think its a "fault" of the adaper, since the flange's surface is just flat. Anybody using Rokkor lenses with adapter on the M has had any similar experience? I already thought of filing off the little metal part so that it doesn't apply so much pressure on the adapter's flange, though before taking such radical measures I'd like to know if there is a better solution.

01maciel Posted December 17, 2022 Share #2 Posted December 17, 2022 There are a few Minolta lenses out there of excellent quality. I have two Minolta lenses, MC W Rokkor 28mm 1:2 and MD 50mm f/1.2. Both are working well on my M10 with a Fotodiox adapter. Never heard about the 22233 adapter. Quote Link to post Share on other sites More sharing options...

pegelli Posted December 17, 2022 Share #4 Posted December 17, 2022 (edited) I see similar metal parts on the aperture ring of all my Rokkor lenses (17/4, 45/2, 50/2 and 58/1.4). I use them on my M246M with a K&F MD to M adapter and this metal part on all my lenses runs free from the adapter. The metal part is probably there to communicate the aperture from the lens to certain Minolta SLR's and for use on your M cameras I think filing it off so it doesn't rub to your adapter is probably fine, but you might jeopardise the operation when the lens gets mounted back on a Minolta SLR.

jankap Posted December 17, 2022 Share #5 Posted December 17, 2022 (edited) I have the 24mm MC and use it with a nameless adapter (MD -L/M) in manual mode. The black metal part of the lens runs free from the adapter. I have no idea what the function of this part is.

Meter coupling tab, similar the the Ai tab found on Nikkor lenses. I think that a good adapter will be machined so that the tab runs free. Why the 22233 binds is baffling since Minolta MC and MD lenses will have this tab. Personally I'd try to source a better adapter than the Leica one. 1 Quote Link to post Share on other sites More sharing options...
UliWer Posted December 17, 2022 Author Share #7 Posted December 17, 2022 Advertisement (gone after registration) I managed to file off just a fraction of a millimeter from this tab and and it was enough so that I can set f-stops normally now. Thank you all for your help! 3 Quote Link to post Share on other sites More sharing options...
pgk Posted December 18, 2022 Share #8 Posted December 18, 2022 FWIW I think that Minolta MC lenses were so called because they were Meter Coupled - that tab! Quote Link to post Share on other sites More sharing options...

I was going to say it was Multi Coated, but now I think you are right https://www.rokkorfiles.com/Lens History.html Edited December 18, 2022 by Pyrogallol Quote Link to post Share on other sites More sharing options...
