PolarPro 77mm QuartzLine Circular Polarizer Filter

BH #POCP77Q • MFR #77-CP
PolarPro 77mm QuartzLine Circular Polarizer Filter
Key Features
  • Circular Polarizer Filter
  • 2.5x Filter Factor, +1.3 Stop
  • Helps Eliminate Reflections and Glare
  • Reduces Haze in Landscapes
The 77mm QuartzLine Circular Polarizer Filter from PolarPro helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a nonmetallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from nonmetallic surfaces and an increase in the saturation of skies and foliage.

PolarPro QuartzLine Overview

The 77mm QuartzLine Circular Polarizer Filter from PolarPro helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a nonmetallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from nonmetallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of autofocus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, autofocus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

This filter is constructed from quartz glass for enhanced durability. To prevent internal ghosting and reflections, 16 layers of anti-reflection coatings offer scratch protection to the filter substrate while promoting clarity and color fidelity. The coatings associated with the PolarPro 77mm QuartzLine Circular Polarizer Filter also result in an improved beading effect when in contact with water or oil, allowing for more efficient cleaning.

The quartz glass is set within a brass filter ring with side knurlings that can be rotated in order to adjust the intensity of the polarization effect. Together, the brass material and knurlings prevent jamming and provide additional strength, as well as a textured grip when mounting or removing this filter from a lens.

Does it make sense to (can you ) add the Natural Density on top of this filter?
Asked by: Patrick
Personally, I would not use a ND filter on top of the Polarpro Quartzline Circular Polarizer Filter,when you can add that effect in post whether in LR or PS. Though you certainly can add a ND filter ,its just my preference not to, plus its less destructive in LR or PS...

Does this come with the same case / cover system that the McKinnon Variable ND filter comes with?
Asked by: Craig
It does not. The PM Variable ND Signature II comes with its round unique protector (hard cover + rubberized cover), and the Quartzline CPL comes with a square hard case with magnetic closure.

Does the rear ring ever bind or cross-thread?

Does the rear ring ever bind or cross-thread?
Asked by: George
The larger the filter diameter the more difficult it is to install without cross-threading. This is not a function of the filter but a function of large diameter fine threads. Great care needs to be taken when starting to thread the filter. Any binding or resistance at all within the initial partial thread engagement is an indication of cross threading requiring an immediate reverse rotation/removal and another attempt at installation.

Is this an ND-16 Filter?

Is this an ND-16 Filter?
Asked by: Daniel
No. An ND-16 reduces exposure about 4 stops. This is a polarizer that will only reduce a mere 1.3 stops. This is mainly used to make skies more contrasty, remove glare and reflections from things like glass and water. If you're looking into an ND-16 take a look at this instead. https://www.bhphotovideo.com/c/product/1418315-REG/polarpro_77_nd16_pl_quartzline_77mm_nd16_pl_filter.html This is a ND-16 with a polarizer (still just 4 stops of reduced light). It's a 2-in-1.

Does this product fit with a lens hood?
Asked by: Karla
A 77mm screw in lens hood or addtional filter will attach without problem. depending on lens though, attention needs to be paid to any potential vignetting that may occur with wide angle lenses. Also, some bayonet hoods may not slip over the outer ring of the filter.

Does this work with a Canon R5 24-105 lens (77mm) - and if so, can I screw it into the UV-Haze filer that I keep on this lens for protection?
Asked by: Susan
Yes, the PolarPro 77mm QuartzLine Circular Polarizer Filter will work with a Canon 24-105mm lens; any 77mm filter will adapt to a Canon 24-105mm lens. We highly suggest using slim-profile filters to avoid vignetting issues.
