Feature(may vary by option.)

●1-11 aperture stops: Slows down the shutter speed by 1-11 aperture levels to extend the exposure time. Excellent for landscape photos and video shooting.
●High-quality material: made of high-quality Japanese optical glass with 18-layer nano coating on both sides, which is oxidation by sandblasting, reduces lens reflection and removes glare.
●【Light Reduction】The variable light reduction eliminates washed images and allows long exposure and motion blur techniques in variable light: use slow shutter speeds and large apertures without overexposing your images.
●Easy to use: the frame is only 7.4 mm thick and has a CNC trapezoidal pattern design. which increases rotation friction and is convenient for installation and removal
●Attention: The position of the X pattern depends on the type of lens and focal length you use, and the dark shadows disappear by themselves when you continue to rotate
