Q. How do you clean a canon t2i kit lens? I accidentally smudged it and I tried using a lens cleanser for laptops and glasses but it didnt work. I tried using a cloth but it sitll didnt work. Any ideas?
Answer
You clean a Canon T2i kit lens the same way you clean all other photographic lenses. You can use:
1--A quality bulb blower like Giottos
2--Anti-static brush, LensPen or simple paint brush
3--Micro fiber or 100% cotton lens cleaning cloth
4--The fog of your breath
First use the bulb blower to blow off any loose particles that may be on the lens and could scratch the glass when it is wiped down. Be sure you got everything using the brush, particularly around the filter ring, moreso than the glass itself. Brush out any little bits that may have gotten trapped around the diameter of the lens barrel and could scratch the glass if dragged over it with the cleaning cloth.
Then, gently breathe onto the glass, being careful not to spit on it. The goal is to fog the glass and provide a thin, even lubrication for the cloth to both slide on and wipe debris into. Next be sure your micro-fiber or 100% cotton cloth is perfectly clean and wipe the damp lens in a circular motion. Do not press hard onto the glass, just let the cloth glide on the condensation. Repeat as necessary but go slow and gently with the entire process. Do not scrub the glass.
If the smudge still does not completely come off, you can use a liquid that is made specifically for cleaning photographic lenses only. Apply it to the cloth and never to the lens directly.
If none of this works, you should take the lens to a repair shop rather than continue trying to tackle it on your own. While cleaning lenses may appear simple enough, it is extraordinarily easy to leave fine scratches all over the front element of your lens in attempt to clean it. For this reason, it is important not to over-clean your lenses. Blow them off from time to time but avoid contacting anything with the glass whenever possible.
Some will tell you to use a UV filter to protect the glass. I prefer not to have optical aberrations in my images that unnecessary filters cause. I don't put filters on any of my lenses and simply care for them with the instructions above (even my very expensive Leica lenses.) If you want to protect your lens, use a hood as these should nearly always be used anyway and they can actually increase, rather than degrade image quality while providing nearly as much protection.
Be careful, take your time and good luck!

How do you clean a camera lens?

I just bought a new Canon "L" lens (the 24-70mm) and was wondering: what is the best way to clean it?
Answer
I've had that lens for several years, and am very happy with it. Here's how to clean your lens and keep it clean:
First, buy a protective/uv filter. This is a clear glass thingummy that screws onto the front of your lens. Keep this on ALL THE TIME. Don't ever take it off. If you want different filters, attach them to the front of this filter. It won't affect the pictures, and it will keep the front element of your lens safe and clean! Here's some possibilities from B&H. This lens uses 77mm filters, so that's what I've linked to: http://www.bhphotovideo.com/bnh/controller/home?A=search&Q=&a=27_307&mnp=0.0&mxp=0.0&shs=&ci=112&ac=&Submit.x=17&Submit.y=18&Submit=Go
The B + W or Hoya filters in the $100 range are fine, although there are better ones available.
After you get your filter in the mail, you need to clean the actual lens before putting it on. Use pec-pads and a methanol-based cleaning fluid (that will evaporate almost instantly with no residue). Use single wipes with the pads; don't go back and forth with the same pad, because you can pick up dust and scratch the coating. Here are some good possibilities:
http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=71154&is=REG&addedTroughType=search
http://www.bhphotovideo.com/bnh/controller/home?O=details_accessories&A=details&Q=&sku=127525&is=REG&addedTroughType=accessory_detail&addedTroughValue=238168_REG
Once it's nice and clean, put on that filter!
In the future, you'll need to clean the front glass of the filter instead of the actual lens. Use an air blower (like this http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=343088&is=REG&addedTroughType=search) and a film/lens brush for light dust, and the pec pads and solution for anything more. Do NOT blow on the lens or filter, since you'll get saliva or particulates on it, and definitely don't use those "canned air" things like Dust Off.
Have fun!
