I was wondering what the concensus is regarding cleaning SLR lenses. I have been told by a few people that it it unwise to use any kind of cleaning solution or cloth to wipe the front of the lense as that will remove any coating that has been applied to a lense.
Is there any merit to that?
How do you clean your lenses? Do you use any solutions/wiping towels?
I haven't had any reason to go about cleaning my lenses as I tend to be quite... well... anal about my equipment.
For instance, when changing lenses I lay the body on its back and as I move the lense off the body, I place the Canon cover immediately in place and lock it into position while I cap the removed lense and I reverse the process to put the new lense in place. |

I tend to point the body 'downwards' when I'm changing a lens - so that the sensor isn't facing up to get dirt falling on to it. I try to use gravity to keep the sensor clean, not encourage dirt to hit it. Dunno how well that works, but I haven't cleaned my sensor in a couple of years, other than using a blower occasionally and I don't really have any noticeable or annoying dust/dirt issues.

I was under the impression that the static charge of the CMOS sensor would overcome gravity, at least in regards to dust particles so it wouldn't matter how you held the body while changing lenses.
I keep it pointed up to be able to quickly line up the cover/lense that I am putting on, minimizing the time that the inside of the camera body is exposed to the 'outside'.
What about cleaning those lenses though? |

Ditto, the only way to go. Has a brush on one end and a special pad on the other. |

I don't change lenses with the power on, so no real static charge. It takes a _long_ time and a lot of power to get a significant enough charge on any cmos sensor to attract dust - that's mostly myth/BS.
I use the red dots to line up the new lens - that's what they are for after all :)
I use a lens pen to clean particulate dust off my lenses and the pad end to remove finger grease or water spots if any get on the lens.
Every now and then I use a canon lens cleaning kit (solution/ wipes) to give the lenses a better clean when appropriate. I typically try to avoid having to clean them at all though - using UV filters when they may get dirty (sea spray, kids fingers, dogs noses etc)

I asked the same question a while back and never got a straight answer. Several people suggested a lens pen, but as yet I haven̢۪t tried one (don̢۪t like the idea of cleaning a lens with powder.) I bought some Eclipse Lens Cleaning Fluid and Pec-Pads Photowipes to clean my camera̢۪s CMOS sensor, and I̢۪ve been using that for the lenses too. It works great and I haven̢۪t seen any problems with the coatings on my Canon lenses. It is supposedly designed to clean sensitive optics, so I don̢۪t expect any problems using it to clean camera lenses.

| take a lens clening tissue and tear it in half. Now you two pieces with 3 straight sides and one ragged. Take one of these pices and roll it up. You then gently use the ragged end to clean in a light circular motion. No rubbing and no hard pressure. Patience will get you there. |

Lens Pen.
Fog the lense with breath, use the small round leather pad to clean glass surface. Find them at photo stores and/or birder stores that sell Binoculars. Very useful tool.
(I should have mentioned that my lense glass only gets cleaned once, prior to the UV filter being attached. From that point on, it is the UV filter actually being cleaned.)
