Tokina 200mm f3.5 Nikon lens on my DS

Well I went to a garage sale this weekend and saw some lens out on a table a Spiratone 500mm which didn't interest me much and a Pentax ZX-M with a 50mm f2
so I see this leather lens case it's a Tokina 200mm 3.5 I was looking for a lens to cure my boredom. It looks like a k-mount so put it on the ZX, and apparently i can't read well cuz it does have the (NI) etched in there. But it fits. so I buy it and try it on my DS when I get home and it doesn't fit all so correctly but it works and won't fall off.

So enough rambling here are some test shots...

btw does the bokeh look weird to anybody else?
and i should have been using a tri/mono but i forgot...







rest of the set...test shots - a set on Flickr

This lens might be a TX lens. If it has a rectangular bulge below the aperture ring with O and L on it, it has an interchangeable mount. You might be able to purchase a Pentax TX mount for it, either M42 or K.

Your NI looks more like IN, and it's placed right where the red mounting dot typically is on a K-mount lens.
Nice shots.

There's no IN mount, it's just telling you to INsert the lens at that point.

OK, not a TX. But it is Nikon, that weird protruding fork is a dead giveaway.

Mock, seriously if you don't know, please don't give wrong advice.

The lens in question has the Nikon AI mount.

A while back, with the help of several people here, I looked into the possibilities of mounting Nikon glass on Pentax K-mount. It turns out there are lenses which will actually go on and lock. This thread here is of note:

Using Nikon F Lenses On Pentax K Bodies (LBA Post): Pentax SLR Talk Forum: Digital Photography Review

Also, as evidenced in this thread, some AI lenses will partially mount. In the end, for me, as much as I wanted to try some great lenses, like the legendary 105 f2.5 on the K20, I could not risk destroying the K20. But, as you can read in the above thread, some people take this risk.

I never claimed to be the authority on it. I held up one of my K lenses next to his photo of the mount and it looked extremely close...sorry. What function does the "fork" perform, if any?

Hi Mock and welcome to the forum. The "ears" serve as the aperture coupler for open-aperture metering and are the signature feature of manual focus Nikon lenses. The slot engages a small pin on the camera body when the lens is mounted and moves with the aperture ring.

Steve

(P.S. Sorry about the gruff rebuff, but Creampuff is right. We need to be careful when making suggestions regarding lens/mount compatibility. The wrong lens mounted to a camera may permanently damage the body.)

Could we see a side photo & front photo of the lens? I'd be interested in getting a look at it.

A tripod mount is nice to have, especially when the extra cropping of a DSLR sensor is factored in, though it might not be a good idea to use it if the lens is only slightly attached to the camera body. The photo from the side is too close to really tell, but I'm guessing it's not the same lens as my Tokina-made Vivitar 200mm 3.5 (it's a T-4 mount, interchangeable camera body mounts). I do have a Hanimex 200mm 3.5 that has a tripod mount, makes me wonder if the two are related, but again can't really judge without seeing the full lens. I have no idea who made Hanimex lenses.
