The action on the variable ring is great. Smooth, stiff enough to stay in place but not so stiff as to unthread or overtighten to the lens. The optical quality is good to great with minimal internal reflection. At 500m / F11 / 1/250 s it's TOO dark for anything but a completely full moon. I'll probably use it more for full snow imaging than the intended purpose of lunar photography but I'll definitely use it.

I had a few issue with light. This definitely helped and made my video 10 times better. This is not a paid review I'm actually real. To prove this is real I'll write cat backwoods. TAC = CaT so make the purchase.

I live in the city and can't bring my lights everywhere, so when I get caught in the harsh sun, I put this on and it help me control some of that lighting without losing my most of my settings... its worth it.... IG: _elijah_photography

For my standard zoom I wanted to buy a variable ND filter and came across the K&F filter. As usual, it arrived well packaged and quickly. A transport box is included. The filter has levels 8 to 2000 and covers a very large area. I immediately tried the filter on my Olympus OMD EM1 MkII, it works great. I could not detect strong vignetting or noticeable color casts. With maximum darkening, one should pay a little attention to segmenting patterns (light-dark). Of course, the K&F filter cannot keep up with large filter systems, but that was not a selection criterion for me and such systems cost a lot more. The price-performance ratio is great here!

I got this to make shooting in bright sunlight easier with the canon 15-45mm canon kit lens. Works great!

Very solid filter and gets the job done. It isn't perfect, but for the price you can't really beat the value. Would purchase again if needing more than one filter in my bag.
