Nice package of three-filters-in-one
I am using the 67mm K & F Concept Variable ND CPL Black Diffusion Filter with my DSLR camera. It is an interesting filter, combining three functions – a variable neutral density filter (1-5 stops), circular polarizer (CPL), and a 1/4 black diffusion filter. The ND filter and CPL filter are controlled by separate rotatable rings. The ND filter ring is marked with five locations indicating the number of stops and does not produce the dreaded X-mark at its maximum setting. The ND filter includes a screw lock to lock a selection in place that is easy to use. However, it protrudes about one-half inch out from the ring, and I am mildly concerned it could catch on something and break. It is working well so far though.
The CPL filter works well to polarize light entering the camera, comparable to a stand-alone CPL filter. The effects of the 1/4 black diffusion filter are subtle and hard to notice, depending on the lighting.
The filter includes a very nice case for storing the filter.
