Years ago I did a study of lens cleaners and tissues because at the "Camera Assistant's Olympics" get together meeting Pancro Lens Cleaner was voted best by its membership. http://www.filmtools.com/panlencleanf.html They also voted for Rosco lens tissues. http://www.filmtools.com/roslentispad.html The results of my study was I would agree with there consensus. I also us Mikros cloths occasionally, and usually after a few uses they are washed with dish detergent and rinsed with very clean water I limit there use because of possible particle contamination that might scratch lens coating. I find the Rosco lens tissues the best of what's out their. I do keep my cleaning tissues is a sealed container to limit particle contamination. I also never clean lenses or filters in the field, and if it is absolutely necessary I find some place indoors, or a vehicle where moving air won't deposit abrasive particles on the class surfaces. My CR33 plastic graduated N.D. filters are another story.
