I got my hands on an old M42 screw mount SMC Takumar 50mm f:1.4 lens. Seems to be in pretty nice condition and didn't cost me anything.

I read a bit through the forums about the available adapters and all the caveats. I've seen a couple of the Pentax made adapters for sale priced around $50 and others ones priced much lower. I think if I couldn't focus to infinity (as with the cheaper ones), I wouldn't really use it much. Is the General Brand one from B&H equivalent to the Pentax? Do they ever have it in stock?

I guess my question is would it be worth it to spend the money for the Pentax adapter? Is this lens worth investing that much money to make it work, or would I be better served applying my money towards something K-mount.

Remember, I'm a DSLR noob and don't know how well I'd take to having to set everything manually on the lens.

unless you collect, $50 is too much.

as far as the general brand at B&H, it's fine. it'll still let you retain infinity focus. it's probably a kalt or bower. i've got a kalt from them($18dlvd) and it works just as good as my asahi model altho it's a little harder to mount and unmount but i don't need the tool to do it with..

Check Ebay for Roxen. That is where I got mine from for like $25 shipped or something. Yes, it allows infinity focus! The adapter is well worth it and opens up and entire line of excellent lenses!

You'll have to be careful with Roxsen, they do sell both types. ... Jack

I use Kalt brand but mount them to the lens semi-permanently with Loc-tite. You have to remove the spring clip to use it this way. They work great as long as you don't accidently dismount them. They need a small groove cut in the lens base so the locking ppin can hold them on...I'll get around to this one day soon. B&H is where I buy mine. By doing it this way they become de-facto K mount lens...Infinity focus is achieved with all of them.

Cheers Jack

Mince looks like the first one you posted - infinity focussing etc.

Same tool as well.

Mine came in a bag with the instructions.
