Feature:
The Profezzion ND filter offers 11 diaphragms to reduce light and an excellent moisture-proof carrying case.
The higher the density, the slower your shutter speed will be. It reduces the number of lights entering and gives the photographer more freedom to control aperture and shutter speed, but does not change the original colors.
The front end of the lens mount can be rotated. Grayscale can be continuously adjusted from ND2 to ND2000 and are easy to carry.
Application: bright light, cascading fog screen and night photography, cloudy and rainy days, etc.

Note:
1. If you use this filter at high ND values (9 or more diaphragms) with wide-angle lenses, the "X" cross may appear on the images, vignetting or blur on the image. Depending on the structure and operation, this is the essential principle of a variable ND filter.
Due to the structure and principle of operation of this filter, vignetting or image blur is inevitable. If this is really not acceptable, please choose a non-variable ND filter.
2. Please confirm the size of your lens by checking the size of the lens thread instead of the camera model name before buying. The size of the lens thread of your camera will be marked somewhere on the lens barrel. In front of this number, there is always a symbol "Ø" (diameter)
3. The front diameter is larger than the back of this filter. Rear wire (to be fixed on lens): 52 mm. Front thread (to attach to lens cap / other accessories): 55 mm.
