I have a nearly perfect new style Elmar-M f/2.8 which needs only a little lubrication to make it perfect. It grabs just a touch when doing fine focussing. So, my question is, how do I go about fixing the problem? I could send it away for a CLA and have a perfect lens back several days and several dollars later. Or, I could do it myself (I'm pretty handy and not too squeamish). If I decide to do the job myself, what lubricant should I use, and will it be sufficient to lubricate the exposed helicoid at the back of the lens?
