I just won this entire lot of lenses, filters and other stuff for $11 on Goodwill. I know the pics are very small, sorry, but can anyone tell me which lens mount these are, and in particular what that Vivitar 300MM is? I actually bought the whole kit at the very last second because I saw I could probably get it really cheap and because it had a Cokin filter I've been wanting (sunset) and don't have. I'll probably re-sell a lot of the other stuff, but I'd probably jump for joy if that big mama lens actually fits something I own! I have a K-mount camera, an M42 mount camera, and a Canon FD camera currently. I figure for $11 I didn't go wrong. I could sell a couple of things and make my $$$ back real quick, but I'm not so sure of what some of this other stuff is really...

Thanks!
