Hoya 62mm NXT Plus Circular Polarizer Slim Frame Glass Filter

The Hoya NXT Plus Circular Polarizer Filter allows the photographer to remove unwanted reflections

from non-metallic surfaces such as water, glass, etc. A circular

polarizer is a must-have filter for every photographer and Hoya's NXT

Plus is a powerful upgrade to the best-selling NXT series. This filter

applies a waterproof top coat to Hoya's polished smooth "clear" glass

for maximum sharpness. There are two advantages to having a premium

waterproof coating: (1) Water beads-up quickly, and easily slides off

the surface of the filter for streak-free shooting. (2) It also makes

the filter a lot easier to clean when dirt, water and smudges make their

way onto the surface. Hoya applies 10 layers of patented anti-reflection (AR) HMC multi-coatings for improved contrast and color. The polarizing film is optical thin with a filter factor of 1.72

for faster AF and improved viewing over standard PL films. The knurled

edges on the front of the filter make it easy to operate when attached

to the lens. The NXT Plus CPL filter frames are precision-milled

aluminum slim frame, making it lightweight and perfect for your super wide-angle lenses.What does a Polarizer do?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. Circular polarizers

are also great for removing reflections from 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.Key Features:• Waterproof top-coat for easy cleaning• Hoya polished clear glass• 10-layers of HMC multi-coatings• 1.72 filter factor• Low-profile aluminum frame
