NEEWER 77mm True Color Variable ND2-32 and CPL Filter 2-in-1 Adjustable Dimming and Circular Polarizing Filter Multi-Coating HD Optical Glass/Aluminum Alloy Frame 【2-in-1 Variable ND & CPL Filter】The NEEWER 77mm True Color Variable ND2-32 and CPL filter combines the functions of an ND filter and a CPL filter, avoiding the need to carry and switch multiple filters, providing a convenient and versatile solution. The hybrid filter is made for 77mm camera lenses. Please check the lens thread size (with the "Φ" symbol) of your camera before ordering. Note: Due to the integrated hand knob, it is not compatible with lens hoods. 【Precise Exposure Control with Variable ND Filter】The limited variable camera lens filter allows you to adjust the exposure in the range of ND2, ND4, ND8, ND16, and ND32 (1-5 stops) by loosening the hand knob and rotating the filter, precisely controlling the amount of light entering the camera sensor. Note: X-black cross may occur when using the maximum aperture due to the interaction between the variable ND filter and certain lenses and focal lengths. *Only opened* 85
