Can you make video how to properly clean lenses?

@Vitaliy_Kiselev I wish I could, but, I have only watched for hours with a friends who is a lens tech in Zurich. He cleaned and fixed some of my older lenses: 16-100 Switar Zoom C mount Fixed a copal shutter trigger on a large format lens De-click the iris ring on Nikkor AIS MF prime lenses. Leica Elmar 50mm 2.8 which neeed a new fron element. In Switzerland the Leica dealer told me parts are not available for those old lenses. Ha, I bought the front element from Leica in the USA for $100 and he told me he gets the optics directly from Germany! Swiss businesses try to create their own economic bubble since they are not in the EU.

I just watched over his shoulder. He overhauled my old Ecair CM3 camera and an old Panon Panoramic camera. I was an AC who brought a lot of knowledge to the film community there and trained a few assistants, so that made his job easier repairing the rental equipment! He had worked in Canada as a camera and lens tech for William White, the Panavision rental in Canada. I'd worked with Panavision in the USA. There was hardly any Panavision used in Europe, but we had a common language with camera experience. We were good friends. He also custom designed shift and tilt lenses and modified gear all the time. This was the fringe benefit of being a camera assistant.

@Tscheckoff Thanks for these videos.

I've done a few cheap lenses for practice - using advice thatt Matthew Duclos has said I have a couple bottles of pancro + kim wipes and I basically take the lens apart, spray pancro on the wipe, wipe and toss the kimwipe aside, then grab a new kim wipe. Then I put it back together minus a couple grub screws that are lost forever in the wooden floor seams below
