LEE Filters 150 x 150mm SW150 Circular Polarizer Filter
Key Features
  • Circular Polarizer Filter
  • For SW150-Series Filter Holder
  • 2.8 to 4x Filter Factor, +1.5 to 2 Stops
  • Helps to Eliminate Reflections and Glare
The 150 x 150mm SW150 Circular Polarizer Filter from LEE Filters is compatible with a LEE Filters SW150-series filter holder and helps to reduce reflections as well as glare by filtering out light that has become polarized due to reflection from a non-metallic 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 non-metallic surfaces and an increase in the saturation of skies and foliage.

LEE Filters SW150 Overview

The 150 x 150mm SW150 Circular Polarizer Filter from LEE Filters is compatible with a LEE Filters SW150-series filter holder and helps to reduce reflections as well as glare by filtering out light that has become polarized due to reflection from a non-metallic 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 non-metallic 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 auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

This filter is non-coated and is constructed from optical glass for clarity as well as color fidelity. When using the 150 x 150mm SW150 Circular Polarizer Filter, the desired degree of polarization is achieved by turning the filter holder it is placed in.

Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° angle from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
Non-coated.
2.8 to 4x filter factor reduces exposure by 1.5 to 2 stops.
Constructed from optical glass for clarity.
Metal filter case for storage and transport.

This a square circular polarizing filter. For those who bought this, how do you adjust it while using it with other filters such as graduated neutral density and still maintain the right composition with the position of the graduated filter?
Asked by: Francis
Unfortunately with this system there is no option to rotate a polarizer independently of a grad filter. I would recommend getting the Nisi holder for 150mm filters. As far as I know, they are the only brand that has round 150mm polarizers for their system and your lee filters will fit in the slots.

How does this compare to the Progrey Titan CPL?

How does this compare to the Progrey Titan CPL?
Asked by: Ken
I'm sorry but B&H does not carry Progrey filters so i cannot comment but I can say that Lee filters are very good and have been used by professionals for many years. Other quality brands include Nisi, Haida, Formatt and H & Y.

question

Is this compatible with the SW150 original (Mark 1) system?
Asked by: Sujatha
I wouldn't know since I don't own the Mark 1 system. But it shouldn't be a problem since the size of the filters is the same.

question

Will this Lee filter fit in the NiSi 150mm filter holder?
Asked by: Andy
Yes, it should fit regardless of which NiSi filter holder system you own. I have both the original filter system that came out before the newest one that has the circular polarizer built into it. As long as its a 150x150 filter, it will work.
