I dropped my Sigma 24-105 and thanks to this filter my lens was undamaged. Pros: Protects lens Greatly reduces reflections Very thin bezel Easy to rotate High quality construdtion Cons: Very thin bezel -- may be difficult to unscrew at first turn

This filter stays on my Sigma 10-20 3.5 EX DC all the time. Thin thread helps eliminate vignetting. Easy to rotate. Great for landscape photography. Can't beat the price and quality.

Leave it on my landscape/travel lenses as a lense protection in addition to a polarizer

I do a great amount of early morning landscape photography and often the location includes water; I desperately needed a solution to lens-flares. This polarizer is the perfect addition to my flare-prone Sigma 2.8 28-70DG. After applying the polarizer I forgot all about the problem. I read another review touting the glare-reducing benefits of a polarizer in portraiture so I decided to pull the trigger on this purchase. Thanks for the advice, this filter works great for eliminating the shine of oily faces. Buy it!You gotta have a good polarizer!

I use this more often than my U.V. When I don't need it any more the U.V. goes back on, but either one is cheaper to replace than a lens. Since I read an article about using a Polarizer for Portraits I've been useing it with great results, someone wrote into the same magazine asking about useing a Polarizer for cars which is my main use for my Polarizers. Don't wait until you take a picture through glass or of some fish and you can only see reflecions of other things to buy a Polarizing Filter. P.S. this is as thin as my other Slim Polarizer but I can screw a filter onto the front of it much deeper.

Very thin but it has deep front threads

Reduces reflection and protects lens

Digitally Optimized (DG) Filters
EX DG filters benefit from Sigma's multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens and filter elements and re-enter the image sensor, creating a ghost image. The multi-layer coating dramatically reduces this effect. In addition to this, an optimum, neutral colour balance is ensured, increasing the white balance accuracy of the digital camera.
Wide Multi-Coated Circular PL
It reduces the glare and reflections from glass and water and other non-metallic surfaces. It deepens blue skies, and saturates the colors. The Sigma circular PL filter is designed to give best performance with AF Cameras. The Sigma wide multi coated circular polarizing filter is very thin, so it does not cause vignetting with wide-angle lenses. You can monitor the changes at different angles through the viewfinder as you rotate this filter.
