McGirton Posted June 22, 2012 Share #1 Posted June 22, 2012 Advertisement (gone after registration) I've got a 5cm / f2 collapsible Summicron and a Summitar with the same specs. I've hesitated to clean (the front part) because we all know how soft the glass on those is and that you should stay away from it. but now I bought Leica UVa filters to leave on there as protection and since I don't want to screw those on a lens that is not 100% clean I'd like to know: what is the best and most harmless way to clean those delicate lenses?

brianv Posted June 22, 2012 Share #2 Posted June 22, 2012 I use some high-grade lens sheets, "Kodak" now Tiffen? I use a bulb blower to remove dust; dab one sheet of paper with Lens Cleaner- I prefer a ammonia/alchohol cleaner that came with my coated eyeglasses; lightly apply the cleaner; bring in a second sheet to wipe off the cleaner while gently breathing on the front glass to keep the cleaning solution from drying too fast. If the cleaning solution dries too quickly, it can leave streaks. why does the term "Be gentle with me" come to mind... Link to post Share on other sites More sharing options...
tobey bilek Posted June 22, 2012 Share #3 Posted June 22, 2012 You get scratches from not removing debris first step. First blow, then dust. Crud embeds in tissue and scratches. You can use micro fiber cloth, but you must protect it from getting dirty. Do not keep in a pocket or loose on a camera bag.. If it gets dirty, that new dirt may scratch the lens. Plastic bag works well. Link to post Share on other sites More sharing options...
250swb Posted June 22, 2012 Share #4 Posted June 22, 2012 I would say dust it off, breath on it, and use a microfibre cloth. Steve Link to post Share on other sites More sharing options...
tobey bilek Posted June 22, 2012 Share #5 Posted June 22, 2012 Just going to add,if blow and dust makes it look clean, stop there. For smoky films or salt water spray or finger print, do the last step , but that is best avoided because that is where the risk lies. Link to post Share on other sites More sharing options...
