How can I tell if my Asahi Pentax 50mm 1.4 SMC is an M42 mount? It is a screw type mount (for my Spotmatic II) with a single pin. It's an awesome lens (build and image quality) and I'd love to use it on my Nikon D7100.

There are two types one without glass for use with macro setups and one with a corrective lens installed to correct for the new focal distance. In any case, the lens will only work on manual mode as the mechanical and electrical auto linkages are not maintained. I have read that the optical element can produce inferior images. I have the glassless type. However I got one with the corrective lens to mate older canon lenses to my digital nikon and it works well. Don't worry about different screw types..the newer pentax mounts are bayonet.

I use my Nikkor lenses on my Canon 5D MarkII with this mount. It's really good. Nice and snug. don't go for a cheaper mount

Yes. Any K mount lens should work, with various restrictions. All M42 screw mounts will work with an adapter. Depending on the age and feature set of the lens you might need to use manual aperture, focus, or metering, though.

Well.... Guesing that you are looking for and M42 to K adapter for pentax, you can search here at amazon or outside, there are many. And the K5 is capable to use an M42 lens with the right adapter.

The Mobius doesn't have a lens mount per se. This is a replacement lens which requires disassembling the camera. The threads are for focusing. Lenses are not easily interchangeable.

Hello Jenny J - yes you need a Pentax screw M42 to Cannon adaptor and you will have to use the lens with manual aperture settings - this vintage lens is from the late 60,s and provides excellent image quality - Cannon also made a 50mm F 1.4 at that period and it is also a very good lens to have

It is not the same. I was going to answer this in much the same way that SoaringBob has. I cannot add anything further than to say it works to adapt my Canon camera to my telescope equipment and agree that it is different from the M42 mount.

All Pentax K mount and third party Pentax K mounts. There are many third party lens manufactures. I recommend visiting www.pentaxforums.com Go to the Lenses tab and read the reviews. You can also post a specific question on the forum. There are many helpful members there to answer your questions.

The Promaster MC 28mm is made in several different mount types from what I can gather. Canon FD, Nikon AI, Pentax K, Minolta MD. In the case of this lens, I believe MC stands for MultiCoated not the lens mount type. You can see several different kinds of you lens listed here: http://www.hockensmithphotography.com/promaster-2-8/I suggest you look back at the place where you purchased from and see if they listed a mount or search the web to try and find out if the lens has some clue somewhere to tell you which mount it was made for. I suspect its not a MD mount type.

Yes - this adapter is designed specifically for the M42 screw type. It works just fine on an old Tokina lens that was mounted on my father-in-law's 1960's Pentax. Make sure, however, that you get the Version 2 adapter upgrade from FotoDiox. The Version 1 adapter from M42 to Canon EOS did not make provision to disengage the aperture shaft in some M42-type lens. FotoDiox was very responsive, and I had great customer support from them. Again, make sure they send you the Version 2 M42 to EOS adapter.

You should be able to get any kind of C-mount or adaptor ring for you Pentax. I had to buy one for my Nikon so this lens would fit. The only thing is it is a fully manual lens so you need to put your camera to manual due to it not recognizing that there is a lens even attached... this is a fun lens to use though. Amazing photos of the moon.

Yes, the *ist takes K-Mount. An advantage-if you still have lenses for old Pentax film cameras-is that you can use them on the digital Pentaxes. Besides Pentax lenses, other makes with K-mount will fit.

I don't have M mount lens so far. But I bought M to R adapter to mate it for R lens. Both adapters mated very firm and tight. They can seperate easily.

Does the lens originally fit on a Minolta film camera? The adapters are for the Minolta MD or MC lens or equivalent. I have several that aren't Minolta brand that work just fine. I'm thinking your lens is not a Minolta MC or MD mount. Google lens type and name and images of the back of the lens and see if you can find a match. Here is a link that might help you. http://rick_oleson.tripod.com/index-99.html. Hope this helps.
