    In 54 years, however, I've never needed or used one, without incident I might add. (so there) I was hoping that someone had run a real comparison with UV, without UV and using optical glass. I've heard that other shooters have noticed color shifting using UV filters. Although I do use UV coated flash tubes to prevent some organic pigments and some food products from flourescing and I have definitely noticed a difference between shots taken with and without those types of tubes. But as we know, to each their own.

    I use a filter if I'm near salt water that's about it. Otherwise I don't use any UV filter and rarely lens caps.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    A long time ago when I had an AE-1, my 50 1.4 had a scratch about 3mm long on the rear element. The lens flared like crazy. I don't know how bad flare was before the scratch, but I doubt it could be that bad. So I assume the scratch caused it and have since shyed away from lenses that have blemishes on the glass.

    It's of course worse on the rear vs the front but permanent markers can be used to diminish the effect of light scattering. Try a few searches.

    I've used clear multi -coated protection filters on all my lenses since I've owned them even my Tamron SP 17mm f3.5 lens which uses a huge 82mm filters ( they actually don't screw into the lens, it has no thread, but into the lens hood that is threaded ) all the coatings on my lenses are perfect because I only clean the filters never the lenses, and if they get marked or scratched I throw them away and replace them

    had a rare vintage TLR lens accidentally damaged by the technician who had the camera for 9 weeks & totally rebuilt it from the ground up, new texture gave the lens more "character". but currently the damaged front element is with focalpoint (for polish & re-coat) with a 50/50 chance of improvement, will see what comes back & work with it.

    Truly remarkable. But tell us, would you toss your lens away if it happened to grow something under the filter because the lens itself was never cleaned? Here's a thought to consider: If you did clean your lens instead of just the filters, you might notice an appreciable difference in image quality since glass surfaces accumulate microscopic residues from things like atmospheric pollution that you can't see on the lens itself. Even if I don't see it on the lens, I see the remains on the KimTech wipes I use to clean with the Residual Oil Remover (ROR)

    Here: Get a bottle of this and give it a shot. http://www.bhphotovideo.com/c/produc...l_Remover.html
    It really works. Read the reviews there too. AND you can use it on filters too. (A multi-tasking product. Imagine that)

    I have at the moment three little bottles of R.O.R I get from my local pro dealer, I usually clean my flat screen TV's and computer monitor and my glasses with it, I have cleaned a few lenses and filters with it in the past, but I'll take your advice Mark, thanks

    I wish ROR came in the 1 liter size bottle ! I wasn't quite familiar with how ROR is used when I first tried it. So during my first attempt, I spritzed a little on a double piece of Kimwipe lab tissue and initially, it left a very slight film/residue that I recall now, people complained about. The trick is to wipe the glass off with a couple of dry lens tissues after using ROR. THAT made a huge difference. I've used it the same as you Benji. Monitors, flat screens, reading glasses.

    I don't know about you, but I never use lens cleaning cloths. My vibe is that they hide debris and particulate matter that may cause scratches to glass surfaces. So I prefer the tissue. But that's just my opinion.

    Thanks for your note, btw.
    Have a great rest of the week !
    Mark
