Pentax M 1:2 50mm questions

I've looked around in the forum and I think I have found the answers I was looking for, but I need to ask, too, just to be sure.

The lens is from my K-1000. Will it fit my K-X without getting stuck on there? (Tried a Sears zoom lens from the 1000 and it stuck. Don't care to repeat that experience.)
Also, the f stop and aperture will have to be adjusted-correct. I love this lens and really want it to work with this new camera. The filters are 49mm and the lens with the K-X take 52mm. What kind of adapter rings do you recommend? I have no experience with those at all.

Edited to add: Sorry-meant to post this in the beginner's section not where I was last reading.

If the Pentax name is labelled on the lens, then it won't get stuck. For everything else, due diligence is required.

I heard about that pin caveat too. That why I limited my eBay searches to Pentax only lenses. I know it's overkill but I wanted to be safe.

The lens will work fine. I've got one myself, and it's a great bargain.

You'll need to turn on the allow aperture ring setting if you haven't already.

Focus and aperture are fully manual, and you will need to shoot in M mode (Av may work) and use the green button to meter for exposure.

You'll need a 49mm-52mm step up ring to use your filters with this lens.

Thanks everybody.
Grillfire, I found a good link here in the forum by searching "stuck lens" and my husband got it off the camera for me by using an automotive feeler gauge-after it took me two days of trying myself, he did it in about 20 minutes. LOL! Also, in that same thread, are detailed instructions for taking that extra pin off the lens. One of these days, I will get that done.

Dave, I read in the manual about the allow aperture ring setting and have already found it in the menu. Thanks for the heads up on the green button for the exposure. I've got a step up and step down filter rings headed this way.

Moved to beginner's forum - a good place for it. See the sticky thread at the top of that forum for more on using manual lenses. As for the ricoh pin, no lens made by Pentax will have that problem.
