77mm Circular Polarizer Filter

It creates not a nice effect on UWA lens such as my sigma 10-20mm. I never liked the pictures taken with it and have found myself not using it at all.

My polarizer ended up being a Bower, not Sakar. That did not really matter as much as the spots that appeared when shooting RAW. These spots arent noticable until you see the pictures, but they show up as small circular discolorations especially...

Great! Works well, wonderful price, There are no negatives what so ever! I only wish Digital Concepts would expand their products even more.....
