I ordered this K&F Concept 82mm Variable Fader ND2-32 ND Filter and CPL Circular Polarizing Lens Filter to reduce the number of items I carry with me on a landscape shoot.

When shooting landscapes, a neutral density filter can come in handy. It's the easiest way to create that smooth water effect for waterfalls, rivers, and other moving water. And, a polarizing filter helps to tame reflections that would otherwise detract from your images. This filter from K&F combines these two types of filter into a single screw-on attachment.

I ordered this is the 82mm size (so that it would fit my largest lens) and I'll use step rings for smaller lenses. Operating is pretty easy. You use your fingers to rotate the CPL and you use the attached knows to rotate the variable ND filter. Based on meter readings, you'll get about a 6 stop reduction in exposure when the ND filter is set to max and the CPL is adjusted. With the ND set to minimum, you'll see about a stop and a half or so of exposure reduction.

I did not notice the X pattern that appears so frequently with variable ND filters. However, that tends to happen more with wide angle lenses, and a friend is using mine so I wasn't able to test that out. Color rendition is pretty neutral. I did not notice any reduction in sharpness, nor did I experience significant flaring. Unfortunately, it's not possible to use a lens hood when this filter is attached. Also, you need to know that the front diameter of the filter is greater than the rear diameter. For example, if you order the 82mm version of this filter, your 82mm lens cap will not fit. Instead, you'll need an 86mm lens cap. Be sure to look at the chart in the listing so that you know what specific size of lens cap you'll need for the filter size you purchase.

Great for video work, the ND filter slides from darkest to lightest smoothly and quietly. I do wish the ND numbers were on the filters instead of dots though, but other than that, it's really great.

Just what I needed. 1-5 stops variable neutral density and cpl in a single filter. Good presentation and product manufactured with very good optical quality.

Good quality filter. Bring lens cleaning cloth. I use it on a Sony A7C and so far it's perfect.

Well made product and at an absolutely competitive price. So far no problem and good image quality.

I bought this filter after reading many reviews and I am not disappointed. It is perfect and suitable for all lighting situations. Excellent investment

Excellently made filter, comes with rigid packaging. High value for money. Mounted on the Sony 16-35 Gm lens :) Perfect.

Works as expected. Packaged well.
