  2. Hoya - 67MM NXT Plus CRPL Filter - Angle_Zoom

    Model: A-NXTPL67CRPL
    SKU: 6434232

    "Good lens filter...Quality filter. Nice high-grade glass. Very happy....Have used a number of Hoya filters over the years. This slim frame filter so far has not caused any notable vignetting with my wide angle lens."

    Product Description

    The must-have filter in every photographer’s camera bag, Hoya’s NXT Plus 67mm Circular Polarizer has 10 layers of Hoya’s patented anti-reflection (AR) multi-coatings so your images show improved contrast, color and sharpness. The filter applies a waterproof top-coat to Hoya’s polished smooth "Clear" glass for easy cleaning of dirt, smudges and water. The polarizing film is optical thin with a filter factor of 1.72 (less than 2 stops) for faster AF and improved viewing over standard PL films. Hoya’s high quality polarized glass is mounted into a precision milled aluminum slim frame, making it lightweight and perfect for all of your lenses including super wide-angle lenses. Despite the slim profile the filter includes front filter threads so you can attach additional filters or your protective lens cap. 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. CRPL’s are also great for removing reflections from car windows, and painted surfaces. 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 screen until you achieve the right amount of reflection control. When the colors and detail look right, take the picture.
