I recently had the pleasure of trying out the K&F Concept 77mm ND4-64 Variable and CPL Polarizers Filter, and I must say, it’s been quite an upgrade for my photography adventures. This 2-in-1 filter combines a neutral density (ND) and circular polarizing (CPL) function, making it incredibly versatile for various lighting conditions.

The standout feature of this filter is its ability to eliminate the ‘X’ cross on images, a common issue with variable ND filters, especially on wide-angle lenses. K&F Concept has leveraged cutting-edge technology to ensure that this problem is now a thing of the past.

The ND filter offers 2-6 stops of light reduction, making it suitable for both cloudy days and extremely bright conditions. Meanwhile, the CPL filter effectively removes unwanted glares from non-metallic surfaces while enhancing color and contrast in your shots. The filter is made of imported AGC optical glass, boasting 28 multi-layer coatings that allow only 0.2% light transmittance, ensuring excellent image quality.

The filter frame is constructed from aluminum alloy and features a CNC-Non-slip design with a putter to help easily adjust the ND stops. There are five stops ranging from Min(ND4) to Max (ND64), making it convenient to ensure the correct ND filter stop is selected.

It’s important to note that this filter is compatible with all 77mm lenses, but be sure to verify your camera lens thread size before ordering. The lens cap/hood should ideally be 82mm for optimal protection and compatibility.
