Hoya 37mm NXT Plus Circular Polarizer Filter

A Circular Polarizer is the must have filter every photographer needs and theHoya 37mm NXT Plus Circular Polarizer Filteris the best value around. Polarizers do one thing: Remove Reflections. Think sunglasses for your lenses. By removing reflections, you reveal the color, texture and detail beneath. So, leaves are greener, skies are bluer, and the beautiful rocks at the bottom of that secret mountain lake are revealed. CPLs are also great for removing reflections from car windows, painted surfaces, or just about any non-metallic surface. Depending on the lighting conditions the effect can be dramatic or subtle but it never hurts to pop it on and give it a try.Circular polarizers are easy to use too. Once attached to your lens simply rotate the outer ring of the filter while looking through your viewfinder or LCD screen until you achieve the right amount of reflection control. When the colors and detail look right, take the picture.Hoyas high quality polarized glass is mounted into a precision milled aluminum slim frame, making it lightweight and perfect for your wide-angle lenses. Despite the slim profile the filter includes front filter threads so you can attach additional filters or that protective lens cap.
