Identifying Sigma lens mount

[piotref1]

Hello o/ 

Today on flea market here in Poland I've found two lenses from which I took one. 

As I expected it won't probably fit my Nikon D3300. I tried googling more about it and from what I got it's probably "Sigma MF 28-70 mm f/ 3.5-4.5 MC Zoom-Epsilon Lens" but it had all kinds of mounts.

 

I'm newbie in terms of photography and such I have only the basic kit. I saw the lens and felt like I need it but without adapter won't be able to. 

And yes. I know that Sigma offers conversion but adapter would fit other lenses in future too so that's my reasoning. Oh and I know that adapter will be prob more than those 12$ that I paid for this lens. 

 

And if anyone knows if it's that lens and price, it would be just nice to know. Don't think I will be selling it soon anyway.

Old manual era lens with aperture level visible there. I'm not familiar enough to identify further from images, but it could be Nikon F, Canon FD, Sony/Minola A, possibly Pentax something too?

 

The Sigma mount conversion only applies to their latest lenses in recent years so that's not an option. 3rd party adapters might be possible, but Nikon has a relatively long registration distance so adapter will either lose infinity focus (like extension tube) or have further corrective optics.

 

Lens spec is nothing special so even if you can't use it, it might be an interesting decoration. You might try using it backwards for macro, if you look up how that works.

I think a friend of mine bought the exact same lens in a camerastore in Bristol for his Fujifilm.
He got an adapter for his. I asked him which one he got. When he answers I can tell you more.

After a bit of more research or better said "luck" saw information about Pentax K mount.. Before it wasn't even mentioned when I searched. Looks similar to it. In few can get more pictures of it.

 

And the info about conversion isn't nice.. But well there's still macro.

Friend of mine also says it's the K mount.

Now to just find some good brand making adapters and see if they are within price range.

The flange distance for nikon is slightly longer, so you need something with an element to account for that. I woulnt bother though. Optically your kit lens will probably be better, its not a prime or anything to benefit from a wider aperture, so save yourself the £10-20, or maybe even more and use it as a paper weight. You can get much better native mount glass online for pretty cheap, and I'm sure there's stuff that will even autofocus, even on a body without an in body af motor.

 

If you wanna experiment with this stuff, sell your camera and get some earlier fuji like an xt10 or xpro1, with a 16-50mm lens (or if you can afford it the 18-55 is much better). Its much easier to adapt and cheaper because you can get completely dumb adapters that are basically extension tubes. I bought 2, 1 for Canon EF and 1 for M42 for under £30 2 years ago and they are even built great. DSLRs, especially nikon's aren't that great fpr adapting glass. (Honestly, nikon has had the f mount for the better part of a century at this point, no need to adapt really, there's tons of used cheap glass out there.)
