46mm Variable ND Filter ND2-400 (1-9 Stop) Lens Filter Waterproof Scratch Resistant Nano-Xcel Series
SKU: KF01.2376
was afraid that it would have problems because it is a variable ND with strange effects, and there were no problems. Neither in the corners, nor at ND400, the truth is that it was a pleasant surprise for its price. It may have a bit of a green tint, but with a minor correction in Premiere I have solved it, between 5 and 10 points on the tint tab towards magenta and that's it. Highly recommended, it only needs to have a stop like the ND2 and ND32 models that are the ones I usually use.

It works pretty well. The best thing is definitely the price, a 9-stop filter at this price is unbeatable. The leather-look case it comes with is also very nice, with a strap for easy access to the filter when you store it. The only problem is that it has some very noticeable cross vignetting (in X) when you go up more than 4 or 5 stops, which (and this is personal) seems more evident to me than in the other variable filters I have, one also from K&F Concept and another from Freewell. Would I recommend it? Well, not for professional use, but for amateur use, yes, a lot.

had the opportunity to try this filter for my Sigma 17-50, and the result is truly surprising. The product looks great in its truly high-quality packaging and is easy to carry in your bag. The photographic performance is high-level at a reasonable price. I find the tab very interesting, it allows for a better grip during work.

Currently use this filter for my Sony A7iii for my videos on social media. Great value for the price and the quality is incredible.

In my search for a 105mm vnd that doesn’t cost more than a new lens, I came across this. I wish there were hard stops & that the darkening were more linear (is that possible?), but otherwise it’s basically perfect. Only a very slight x vignette at max strength; very little color shift if any.

Great for stopping down exposure if you need to keep your shutter angle and aperture consistent throughout the shoot.
