My neighbor is new to shooting. He recently purchased a K20D and asked me what lenses would be good but cheap. I told him to check out the M42 lenses on ebay. Well, he found a 50mm Mamyia SX f/2 for 20.00 USD and won it.
I found out about this yesterday when he offered to sell it to me for 10.00 USD. He told me he did a little grinding on it so he could mount it to his camera...
PICS
Images not the best, I think my hands were shaking when I saw the lens...
I bought it from him after testing it. Everything seemed fine, and for 10.00 USD, what the heck.
Some sample pics from the lens..

Why would he need to grind the lens like that? It looks like an M42 and should have fit on the K20 no problem!

I have this lens. Its not quite a standard M42.
This series had an extra pin to transfer aperture infor for open-aperture metering and a moving flange it goes on. You can of course remove the pin, but that flange may still interfere with the mount. I haven't tried it on my K100D as I still haven't removed that pin. The pin/flange goes on the outside of the lip of usual M42 mounts like on the Spotmatic. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Yes, he complained that the flange wouldnt allow the lens to mount.
I asked him why he didnt try to remove the bottom assemly and grind it down proper. I guess he just didnt know how to approcah it.
In any case, he didnt do any damage as far as usage is concerned. The lens works perfect, but BOY is it ugly... _________________ Nikons : F4-EM-FG-FE2-FA-EL-FTN-N2020-N70-F Nikkorex

Some Mamiya-M42-lenses can be mounted to an M42-EOS-adapter but the aperture ring cannot be turned then. Perhaps that was also a reason... _________________ Personal forum activity on pause every now and again (due to job obligations)!

I have a Auto Mamiya SX 55mm f1.7 which I wanted to use on my Pentax dSLR via M42 adapter.

- secondly would mount with it's aperture ring that tight on the camera body making it impossible to set apertures ( unless I unscrewed the lens a bit first )
I have not yet sanded down the aperture ring and thus have not used the lens at all.
Could it be that all Auto Mamiya SX have the same problem, at least when mounted on a Pentax m42 > K mount adapter? From what I see here: http://freenet-homepage.de/stauber/mamiya-nc/m42_lenses.htm I would suppose so. But from how the Auto Mamiya ( non SX ) look I suppose that those might not have these mounting problems.
( curious now if I will have success in removing the aperture ring first to do a better job grinding )

Hi Andreas,
Not all Mamiya SX lenses have this problem. I have the 90-230 zoom and that one is OK on an M42->PK adapter after removing the pin - which is a reversible operation on that lens, but not on some of the others.
I have the 28/2.8 SX also, and that one looks like it will give trouble. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

I have a 55mm Auto Sears/Sekor SX 1.8. It has the pin and flange problem. I havent had the heart to grind it down, it just sits on my shelf and goes unused. I would modify it if I could do it right. I wouldnt just hack it like my neighbor did. _________________ Nikons : F4-EM-FG-FE2-FA-EL-FTN-N2020-N70-F Nikkorex

Yeah, when I first saw the lens, my jaw dropped. The lens however does work and can be used now, so thats a plus.
My neighbor has decided to go the auto-focus route. he had enough after this experience with the Mamiya, plus he claims his eyes are too bad for the MF lenses. _________________ Nikons : F4-EM-FG-FE2-FA-EL-FTN-N2020-N70-F Nikkorex
