Great Variable ND Filter for the price

This is my first variable ND filter and Im very happy with it. I got the 77mm version because its a very common size and I already have three lenses that it could fit. Plus with adapters, I can get my smaller lenses to work as well.
The filter. Overall its great. Metal construction with a very smooth ring.
The stops are marked on the ring and the overall construction is very good.
Again this is my first variable ND and so far I'm enjoying it very much.
Price is affordable too.

These is my 2nd variable ND from K&F. The quality it's good as Tiffen and others manufacturers. Instead of have a lot of ND of different sizes it's better have a variable ND for my photography work and save same money.

The only CONS it's the protective case that came with the ND. It's nice but too big.

No X-pattern, virtually no color cast, and a 1-5 stop range (vs. the more common 2-5) make the Kentfaith True Color ND Vario the best variable ND on the market for most situations. Technically, a little extra warmth can be noticed in head-to-head comparisons, but it's almost impossible to tell otherwise and close enough to be matched in post with no ill effects on compressed photos or video.

I wish the IR filtering was implemented in True Color, but perhaps the technology used here doesn't allow for that. Because IR is not filtered, certain lighting conditions can be undesirable or even unusable, especially when more visible light is cut off. Assuming (possibly erroneously) that one flaw is a necessary compromise for the True Color's unmatched color accuracy, I feel the True Color ND-Vario is as perfect as a VND can get, and first VND that doesn't feel like a compromise between accuracy and practicality.

Here's hoping for a true color version of their 5-9 stop next!

I've had variable filters before, but I've never been happy with the dreaded Xs on the screen when spinning or the uneven color cast across the screen, and they's great, very even light reduction across the frame and no Xs. I have the 77mm filter, it is very well made, 77mm so no vignetting in the corners, the small disadvantage with it is that I can not fit the filter with my hood, but no big deal. We recommend.

I chose the ND filter with a 77mm pitch to be able to use it with my Nikon lenses and possibly use adapter rings for smaller increments. Well packaged and easy to use. Easily correctable with slight dominants in post production. Very precise packaging that allows you to take it with you in total safety. Equipped with a Frantal ring with the various corrections indicated. Switching from one tier to another is easy and smooth. It can be used in both photography and video and easily achieves good results. We recommend buying specifically for value for money. Ideal for landscape photos and always to have with you.

I have both a tiffen vari ND and this one. And I like this one even better! My tiff filter has a slight bluish tint and it doesn't even turn too far. I also like that it has a hard stop and therefore doesn't have any x patterns. Quite the opposite of meeting.

In addition, the k&f filter can filter out almost 1 1/2 stops more light than the tiffen, without a vignette.
If I hadn't already bought the Tiffen I wouldn't have it in my camera bag anymore. So he lies around and is no longer used.
