The111 0 #1 December 6, 2009 On both of my lenses, after years of use, there are lots of blemishes... not so much scratches, but more like "dots" probably from impact with particles. On my SLR, I have a UV filter to protect the expensive lens, so I will just replace the filter. But on my CX100, I have a Century .55x with no filter, mainly because I don't think I can use one there (?)... but also it's a relatively cheap lens, so if I have to replace it, it's not the end of the world. And also scratches/imperfections don't really show as much in video as they do in photo. But, I was wondering if there is any way to polish the Century .55x front surface to remove the imperfections, without damaging the lens? I seem to remember having this conversation with Spot once but now I can't remember...www.WingsuitPhotos.com Quote Share this post Link to post Share on other sites
DSE 3 #2 December 6, 2009 Sebum/nose oil and a microfiber won't work? The coatings are fairly fragile. You might want to take it to a camera repair shop to have them refract it and see if the blems are through the coating. If it's engine oil-caused, it may well be through the coating.

Ragnarok 0 #3 December 7, 2009 I have used Mothers Mag and Aluminum polish on non-coated lenses with great results. It is a very light abrasive and even works on plastics. I have even used it to clean CD's up with. I use it to keep my sunglasses polished, as well. Just make sure the lense is non-coated._________________________________________ Twin Otter N203-Echo,29 July 2006 Cessna P206 N2537X, 19 April 2008 Blue Skies Forever Quote Share this post Link to post Share on other sites
DSE 3 #4 December 7, 2009 Like it says in my OP... "Coatings are fairly fragile" and yes...an abrasive will eat them right off. Quote Share this post Link to post Share on other sites

mnskydiver688 0 #6 December 8, 2009 For future reference I put a UV filter on the front. I believe it is a 43mm size. Whether or not you want to put a filter on a $100 lens is up to you but if you can extend the life why not.Sky Canyon Wingsuiters Quote Share this post Link to post Share on other sites

Hmm, for some reason I had concluded long ago I couldn't use a filter with it, and had come to take that for granted. Guess I was wrong.
