Excellent and practical
This is a high quality circular polarizer variable neutral density combination filter from K&F. I used the 77mm to cover most of my lenses using step up rings. The smallest filter size is 52mm as shown in the photo. The filter is excellent for everything it does and it is inexpensive. It's much more convenient than separate filters; it is quicker to use and requires less carrying in your pocket. This also works for some wide angles, which would be a problem when stacking multiple filters. The build quality of the filter is excellent. A leather storage case is included. From 4 stops onwards there is a slight vignetting and color shift, which increases with increasing ND filtering. This is expected and can be fixed in post-processing if desired. Image sharpness and sharpness are not affected. This filter outperforms other CPL+ND filters I have used.
