Right... btw, the SA 21 f4 in bayonet mount is indeed a screw mount one with a factory-fit adapter (secured by a very tiny nut) : but this specific adapter afaik was never listed by itself.

Would you know how to differentiate an original screw mount from a bayonet mount one? I ask because my copy came with a seemingly similar adapter as the one shown in your previous post yet there isn't the slightest mark on the lens barrel where the screw is supposed to fit in. I mean no hole at all. Edited April 11, 2020 by Jul precision Link to post Share on other sites More sharing options...
luigi bertolotti Posted April 11, 2020 Share #25  Posted April 11, 2020 (edited) Here ìs my Super Angulon 21 f4 in Bayonet Mount, with the factory adapter removed : there is a tiny threaded hole along the base ring, and another on the adapter (the screw, or better to say the nut, is SO little that I'd need to arrange a macro setup with bellows (using my M240, not the cellphone..) to enclose a picture of it... 😎 A SA 21 f4 sold as a screw mount item has not the hole - only difference afaik ; as a vague thought... I wonder if the hole and the adapter were made in Leitz Factory... the Super Angulon 21 f4 , though marked "leitz Wetzlar" was actually manufactured by Jos. Schneider (which held the patent for Super Angulon name & design) , and indeed the chroming of the lens is definitely different from Leitz made lenses of that time... it's a lot more shiny (but the adapter too... maybe also it was made by Schneider) Worth noting., many Sa 21 f4 have "LENS MADE IN GERMANY" engraved on the base ring... just over the hole : this one does not.

Thank you for the clarification. I will arrange a quick photo shooting for mine soon to show how it differs. Seems I've been lucky… Someone might have thought it would be easier to sell a screw mount copy as a bayonet mount one. It came with what seems to be a period correct B+W chrome filter which is from Schneider as well. There is the "LENS MADE IN GERMANY" on the base ring AND "Germany" on the focus ring which is a little redundant… 1 Link to post Share on other sites More sharing options...

I think I bought it soon after I got my 21mm f4 screw fit Super Angulon from him, he said it was an early adaptor possibly for that lens? Though as it has M2 as well as M3 engraved on it it can’t be very early in the M camera times. Edited April 11, 2020 by Pyrogallol 1 Link to post Share on other sites More sharing options...

Since Voigtlander quit making their adapters, CameraQuest now carries Rayqual. I assume all 28s have 7:00 infinity locks. I have an 11:00 50 Elmar and no adapter works with the lock.

Thanks ! But I continue not to see relation between the SA 21 and such a long cutout... 🙄 ; the Elmar 35mm with short focus was discussed recently in the LUF... here is a picture of it : afaik , the only lens with knob that has an extralong focus rotation (around 330° - 340°, by sight) Welcome, dear visitor!

I'm even not so sure that this lens has the "infinity catch" and the "bell push" knob which justifies the cutout..

Pyrogallol Posted April 12, 2020 Share #31  Posted April 12, 2020 Yes, I don’t actually see what connection it would have with the 21mm S-A. The 11 o’clock Elmar I tried on the long cutout adaptor fouls when you depress the infinity catch, a pin push version. But whatever lens you use, once you move it off the infinity position the lens has started to move away from the camera body so is clear of fouling on the adaptor. Can there be any other reason why there are different versions of adaptors with different length cutouts? I have two here, both marked 90mm for M2 and M3, one with a cutout the other not, but I can’t think of any 90mm lens that would need the cutout to clear an infinity catch? Welcome, dear visitor!

luigi bertolotti Posted April 12, 2020 Share #33  Posted April 12, 2020 (edited) Jul... about the above picture : The chrome ring under the lens' body is part of the rear cap ? Or is it the M bayonet adapter ? In this case there's something that looks odd, to me... Edited April 12, 2020 by luigi bertolotti Link to post Share on other sites More sharing options...
Jul Posted April 12, 2020 Share #34  Posted April 12, 2020 It is the adapter. The lens' body is unscrewed just enough to show it fully. Now I'm curious about what looks odd… ? Link to post Share on other sites More sharing options...

OK... nothing odd given your answer... 😉 : I meant that the adapter looked not screwed on... So,yes, that's the original adapter... like my one visible in my above picture, with its small hole (and the nut into ? cannot see well..) ... but not corresponding hole on the lens : it clearly was an original screw mount item.. I suppose its serial number is in the 1.6xx.xxx range... ; afaik, the adapter was not available as a commercial part : but probably an official dealer could order it as a spare. Edited April 12, 2020 by luigi bertolotti Link to post Share on other sites More sharing options...

A little higher: 1714XXX. This site's wiki says it was a M mount only batch. It seems at least one screw mount sneaked in. Link to post Share on other sites More sharing options...
wlaidlaw Posted April 12, 2020 Share #38  Posted April 12, 2020 The technical term in English for these small screws with no head is a "grub screw". In German I believe it is: "Eine Madenschraube". Wilson 1 Link to post Share on other sites More sharing options...

Pyrogallol Posted October 30, 2020 Share #40  Posted October 30, 2020 (edited) Back on the subject of Leica screw to bayonet adaptors, I just bought this one. Really just because it is only marked 13.5cm. Would I be right in thinking it is an early version made before the M2 camera came out with the 35mm frame ? Does anyone collect these adaptors and make a study of the variations in engraving and cutouts ? This one is engraved in upper and lower case lettering with the focal length in centimetres whereas the others shown in this thread are in uppercase only and in millimetres without mm or cm after the number. Are they worth a thread of their own? (As well as the thread inside them !) Welcome, dear visitor!
