Hoya 88MM NXT Plus Circular Polarizer Filter with Low-Profile Aluminum Frame and 1.72 Filter Factor

A Circular Polarizer is the must-have filter for every
photographer and Hoyas 88MM NXT Plus Circular Polarizer Filter is a powerful
upgrade to the best-selling NXT series. The new filter employs a waterproof
top-coat to Hoyas polished smooth Clear glass for easy cleaning. Dirt,
smudges, and water wipe away easily. Using 10 layers of Hoyas patented anti-reflection
(AR) multi-coatings your images show improved contrast, color, and sharpness.
The polarizing film is optical thin with a filter factor of 1.72 for faster AF
and improved viewing over standard PL films.
Construction
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 your protective lens cap.
Why use a Polarizer
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. CRPLs 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.
Performance
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 details look right, take the picture.
