Circular Polarizer-M ND16 Filter

Circular Polarizer(CPL) helps to deepen and enhance the color saturation. It is also used to reduce the reflection and glare on the surface of glass windows, water or foliage.

SHV CPL is specifically developed for maximum polarization performance (up to 99%). Its strength lies in significantly reducing surface reflections (note: 100% metallic reflections cannot be eliminated) and diffused atmospheric light, while enhancing overall color saturation and contrast (sunlight enhancement may slightly shift tones toward yellow). The trade-off is that under clear blue skies, it may cause uneven deepening of certain areas, such as making parts of the sky appear deep blue or blue-black.

CPL-M, on the other hand, is based on the SHV CPL design and incorporates an additional 4-stop ND light reduction effect. Therefore, its polarization performance is equivalent to that of the SHV CPL.

PURE Hybrid CPL is STC’s globally unique coating technology designed to render natural, evenly balanced scenery that closely matches human visual perception. It moderately reduces localized reflections and atmospheric haze, restoring more scene details without causing color shift. With an ultra-low light reduction level, it doubles as an excellent polarizing and protective filter for travel photography. However, for situations requiring stronger reflection suppression, switching to the SHV CPL is necessary to achieve up to 99% polarization.

Please note: Reflections cannot be fixed in post-processing, as overexposed highlights lose recoverable image data. To effectively control reflections, a proper filter must be used during the initial capture.

ND (Neutral Density) filter is used reduce the light comes into the lens without changing color balance. This allows you to slow your shutter speed to create the classic motion blur of a moving body of water.  

This CPL-M ND16 filter is the two-in-one functional filter and with slim frame and easy to carry. Our lens is a constructed from multilayer optical material that can convert natural light into linearly polarized components. Just changing the etching arrangement spacing allows more light through to get a uniform polarization rate of 99% with 6.7% transmission for more natural-looking pictures.
 

We polish our lenses to a flatness of ±20μm and 3 Newton's rings for optimal imaging, with no bright spots or impurities above 60μm. Then we add our eco-friendly EU RoHS 2.0 standard double-sided multilayer nanocoating that is hydrophobic, anti-reflective, anti-smudge, wear-resistant, and antistatic, making it very easy to keep clean while also defogging quickly. 

For the rim, we use precision machining for a tough but lightweight aluminum alloy frame. The super slim 6mm design reduces vignetting when using a wide-angle lens. The inner circle is treated with non-stick Teflon and a matte black finish and the embossed frame is easy to rotate. The shock-absorbent frame also reduces the chance of damage to your lens if it takes a knock.
 

Patented Ultra Layer coating blocks UV light below 395nm, preventing haze and color cast in your photos.
