louispreynolds Posted May 20, 2014 Share #1 Posted May 20, 2014 Advertisement (gone after registration) I was wondering if anyone has ever lubricated a lens before, if so, do you know how to lubricate a 50mm sum micron version 1. I Know tat you are able to take the whole lens away from the focus ring/mount which would help keeping the elements clean. any advice?? Link to post Share on other sites More sharing options...

wda Posted May 20, 2014 Share #2 Posted May 20, 2014 A version one lens is old and might not have been used for some time. Lubricants dry out. Try exercising the focusing repeatedly, gently at first, and see if it gradually eases. This often works for me. Otherwise, if deemed of value to you, a qualified servicing would be the answer.

jaapv Posted May 20, 2014 Share #3 Posted May 20, 2014 If you over-lubricate which is easily done you will get oily aperture blades. A minuscule drop of silicon oil on the brass of the helicoid sometimes does wonders. Link to post Share on other sites More sharing options...
k_g_wolf ✝ Posted May 20, 2014 Share #4 Posted May 20, 2014 A Leica/ Leitz lens is a precious beast in most cases and deserves the attention of an expert, should it develop a problem. Try to get it serviced properly - in case jaaps suggestion does not work - and you can expect many years of faithful service. Best GEORG Link to post Share on other sites More sharing options...
louispreynolds Posted May 21, 2014 Author Share #5 Posted May 21, 2014 Thank you, I feel as though it does need that expert service…i think the helicoids need cleaning and relubing as they are filthy and black. Anywhere good and inexpensive in the UK? Link to post Share on other sites More sharing options...
Fgcm Posted May 21, 2014 Share #6 Posted May 21, 2014 Just to prevent anyone from DIY: common grease available from DIY stores is too thick and prone to propagate into the inner part of the barrel. The cost of a small tube of a proper grease, including shipping or the cost of the time spent searching for it, is of the same order of magnitude of a CLA done by an expert.
