Summary: Worked well until I tried to clean it

Comment: This filter did its job admirably for nine months. After that time, I noticed some film/gunk buildup on the front of it. I took the filter off the lens and used distilled water and a cloth to clean it using very light pressure.

After cleaning it, there were tiny scratches all over the surface of the filter. So cleaning the filter ruined it.

I'll try buying the Hoya filter and see if that holds up better. A product like this certainly shouldn't be scratched into unusabilty the first time you clean it.

Summary: Not what I would expect from Canon

Comment: I just assumed that Canon would make a top quality haze filter, so I ordered it along w/ my new D40. The camera is great, but the filter was not, so I returned it. A local camera shop pro showed me how inferior it was to the equivalent filter by Hoya, which reflects almost no light, while the Canon reflects a great deal. The Hoya filter costs more than the Canon, but it certainly seems stupid to try to save $30 when you've invested $1000+ on a camera, especially when the filter directly affects the quality of the pictures -- which, after all, is what it's all about.

Summary: no change in pics

Comment: doesn't seem to make any difference in my outside photos, but i do appreciate the added protection

Summary: good

Comment: I am a beginner in photography and I am aware of the debate about using a filter and not using a filter. I chose to use one to protect my lens although it seems a little expensive for what it is. This filter is easy to install on the lens and remove for cleaning. It is working as I expected it to.

Summary: Canon 72mmUV Haze Filter

Comment: This filter is a must to have in your accessory bag! It works wonders with the color images and making them as vibrant as they are intended to be!
