I have a 50mm f1.4 of that same mount. Actually a gorgeous lens. It came on a non functional Nikon EF that a friend gave me.

this is a vivitar 24/2.8 auto wide angle, serial: 37727713, hoping to score a 24 for cheap (I'm a novice), this one looked good.

JeffJS - you mentioned it "JUST goes on the k mount" does that mean this nikon mount can fit onto a k mount cam without an adapter?

thanks so much for the help, all.

the nikons as i understand it (of this vintage) can attach, though they don't lock in place, they will of course be full manual as would an m or older pentax lens. if you can get this for say 10-20 bucks then no big deal. much more than that and i would watch for the same lens in a k mount (averageprice in the reviews is $48, the KA version average is $76.33, the very fast series 1 1.9 version averages $120

Yes, It will go on the K mount. However, if you look at the black guard around the rear glass, it protrudes just enough (on my 50) to prevent it from going all the way. I will turn just enough to keep it from falling off. If I didn't already have so many Pentax 50mm options, I would mod the lens so it would fit properly.

Ignore the weird look of the eyes in this photo. It's a piss poor attempt at curing doggie demon eye when shooting him with the flash. The photo was taken with the Nikon 50 on my (then) K7.



I've never tested it beyond that however so I don't know what it does at infinity but for anything from 14 inches or so up To infinity, I would say it's a usable lens. Barring mounting it directly on the camera, one could also get a reversing ring and it would probably make a hell of a macro.

That silver looking attachment on the aperture ring, I believe, is what tells the Nikon camera where the aperture is so it can pick a shutter speed (similar to our Av mode). I had some Mamiya Medium format equipment with the same arrangement.

I just noticed the discretely-etched N on the mount

It's Nikon and you can use it on your camera. You can put it 180 degrees turned on your K-mount, remember those Nikon's turn on the wrong way, just can't click it good, so you have to hold it otherwise it will tumble on the floor.

I have an adapter for Nikon to K-mount, but only usefull with really good glass.

The rabbit ears are dead giveaway that the lens is a Nikon mount.

It looks like a Canon FD but I don't see an orange alignment dot. That was the mount Canon used prior to dumping their prior customer base for the current ef mount of the EOS system. Prior to the FD was the related FL mount.

Yeah, that's a Canon. Probably an FD. Not good for Pentax.
