K&F MV35 67mm Variable Waterproof ND8-ND2000 Filter with Multi-Resistant Coating

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

Before every business trip I try to upgrade my gear.I already have a number of fixed ND filters for video however every so often, you want to have some flexibility or "just in case." As such, I picked up this variable ND filter from K&F.Overall impressions are quite good .The filter feels solid, there were no imperfections on the glass upon delivery and it came packaged well in its own case. This filter case is slightly bigger than the one I picked up with my CPL filter from K&F.The filter screwed on and off the lens with no issues and functioned smoothly, changing from low to high (ND8 to ND2000). This is a free moving ND filter so there are no bump stops, etc. Dial it in to what you have. The filter, as you can see in the pictures does come with easy to see markings.The only things to be aware of, and this is my first variable ND filter... while my fixed Hoya ND filters easily functioned with the lens sun shade, the variable ND filter is a bit thicker. In any case I suppose you would not be able to adjust it if the hood was on, unless you have a cut out in your sun shade.Overall, good filter, and while it is not cheap junk sub $20... it is certainly not going to burn a hole in your wallet.3 year warranty is a plus.

I’ve heard nothing but good things bout k&f filters,so i had to try one for myself . I’m nothing short of amazed, these filters are amazing I’m mad at myself for waiting so long to purchase these will be the only brand of filters in my bag!

I shoot a lot of video with my Sony a7iii and often outdoors in the middle of the day. As any filmmaker knows, it can be very bright during this time and if you want to follow the 180 degree shutter rule, then you will need an ND filter to cut off some light. This ND filter does the job very well and the best part is that it is also a variable ND filter meaning that instead of taking the whole ND filter off, you can just turn turn the filter manually to adjust it's intensity. I got the 82mm since that's my largest lens and if you do this, you can just buy step up rings to adapt this to different lenses with smaller filter threads.

Obvious vignetting and big "X" at high ND levels. Of course at this price you can't expect a perfect product. But these defects will affect photo quality. So I choose to return it. If you don't mind, use the low ND levels and it works fine!
