The Singh-Ray LB Warming Circular Polarizer is the next bold and innovative step in Singh-Ray's development of polarizing filters. This filter has increased its light transmission capacity by 60% - no small endeavor. Basically, they're talking about a 2/3 stop increase in brightness.
This filter also has a warming element to it which can help when it is either overcast or if you're shooting in open shade.
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast.
The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems)

This is something I need exactly for my new Nikon D3s camera with the new Nikon 24-70mm, 70-200mm zoom. I was recommended by a friend of mine of this Singh-Ray filter & it's the first time I buy Singh-Ray product. I will definitely buy other filters from this company. The quality is good & the case the nice.

Overall, the polarizing filter performs as I expected it to perform...nothing short of spectacular. I will continue to purchase Singh-Ray filters in the future. Additionally, the filter came with a nice case that keeps the filter protected when not in use.
