How can I loosen a tight focus ring on a new Nikon 50mm manual focus lens
Will just useing it loosen it up a bit. I notice that with diffent used and new nikon manual focus lenses some are rather loose and some tight to turn. I do alot of street photography where speed of focus is important and I am used to manual but I was hoping someone can tell me what I can use to loosen this lens up. Is there some safe lubricant out there maybe.

I have a Richoh 28mm lens for my older system that is so tight, it's almost impossible to focus on the fly. So, often I'd use it in bright light at f/16 and just rely on the depth of field to get me close to correct focus for the subject.
There's nothing "safe" you can do to loosen the focus-collet. You could try contacting Nikon repair and ask if they'll consider this for "repair".

Being that the lens is a manual focus lens, there is a chance that in might have been sitting un-bought on the shelf for quite awhile... sad but possible.
There might be a chance that the solid film lubricant has "solidified" a bit too much from lack of use since the construction of the lens. I also participate in a Leica site in which all of the lenses are manual focus, and this question comes up very often. Many people report improvements in the ease of focusing by sitting in a chair for the length of a TV program, and simply racking the focus ring from infinity to the closest focusing range... over and over. This process will "wake up" the lubricant and the action should smooth out.
The other major cause of tight focusing action is a lens that has been dinged, causing the mechanism to go "out of round"... in other word you would be trying to rotate an ellipse instead of a perfect cylinder... not too easy. Assuming your lens is truly new, this shouldn't be your problem. Try the high repetition method as stated above. Hopefully you might see improvement... at least it is free.

Al's method has worked for me with an old Meopta-Flexoret twin lens reflex camera that was so stiff you needed to beat the focus around with a lump hammer. The heat of your hands will also help to get that old lubricant moving again. But whatever you do, don't be tempted to put any oil in... you'll wish you hadn't!
