Please help. I have a D5100 and recently purchased a "Rokinon 135mm MC f/2.8 Ai lens for Nikon manual focus" and am battling to focus this lens.

I set the camera on M and have used live view and "see" the image on the screen in perfect focus - when I shoot the pic and check it out on the Mac, it's slightly out of focus. Some pics are better than others but even the better ones are not very good.

The lens is in very good condition and the seller has a 60 day return policy. I paid $100 for it.

As a newbie, I thought about going the "vintage lens" route as they are far cheaper and can give could results from what I've read (Ken Rockwell). There have been good posts about the Rokinon 135mm f/2.8 so I thought it was a good deal. Let's hope it's just finger trouble on my part.

Any help would be appreciated.

Thanks,

Norman Silva.
