Is there an adapter for my kalimar lens on a Nikon body?
So I was rummaging through my attic and I found my dads old film camera and he had this Kalimar 50 mm lens. I was wondering if there's an adapter for that specific lens on a DSLR Nikon ( D3000)
And if there's could you attach a couple links. I tried looking it up but I don't know what to look for.
Thanks so much!
Added (1). It was on an Olympus OM 10 if that helps.

Sony a33, a35, or Nikon D3100?
I've been doing a lot of research on cameras and I've got it down to these three. I've already checked the prices on them and they're affordable for me, so price isn't a problem. I really can't decide which one to get because they all seem so similar. I'm not very knowledgeable with cameras, nor am I a professional photographer. I guess you could say I'm just your average user, looking to better my photography skills, and I want a very good camera to help me do that. One thing I like better about the Sony's is that their screen resolution is higher than the Nikon. And I really like the flip out screen on the a33. But that all isn't really important. What matters most is image and video quality. And that's what I really need help with. So please let me know which is better. Also I'd like to know about your experience with these cameras if you've ever owned any of them.
