Accurate color reproduction, allows me to thread on a lens hood. The 67mm uses a 72mm lens hood to protect from rain and hits to filter to protect from scratches. The CPL filter allows better contrast and color pop when used outside than can otherwise be obtained. Only negative for me, no hard stops to know the VND settings which is to be expected in this price range.

Very impressed by this 77mm VND+CPL filter. Did not notice any color cast. The rings has a good amount of friction, not too loose. The only cons is that this filter is over sized so it won't work with lens hood.

Works perfectly on Sigma 24-70, used it in different daylight situations, works perfectly. The Polarizing filter is an extra benefit!

I'm still in the testing phase of this filter but so far it's working great with little to no color cast. However, the CPL is a little tough to use as it's a little fiddly and not clearly marked for ease of use.

Works well, have several

K&F products are usually an example of a good product at a good price, but in this case they have gone above and beyond, and while maintaining a good price, the result is an extraordinary product. In this model, the color reproduction is excellent, avoiding the yellowing effect of other similar filters. In addition, its frame has a self-locking system that prevents the appearance of the "X" pattern when high neutral density values are used. It stands out for its absence of color casts, even in the darkest neutral density settings. Made from premium Japanese optical glass and with 28 layers of nano-coating on both sides, it effectively reduces reflections and stray light. In addition, its hydrophobic, anti-scratch and anti-fog treatment guarantees a sharp, blemish-free image. Unlike other models, it allows the polarizer to be rotated independently of the neutral density setting, offering total control over the image.

This is really cool, I used to carry some ND filters and a polarized filter, but now I got both in one unit The adjustments are easy to make independently, but you may need to hold the ring. The finish is good, very professional look.

have been universally happy with the 8 K&F products I have purchased so far, so I was excited to try out their True Color Variable ND CPL filter. Like my other K&F products, the build quality is very high - probably their best yet. The filter rotates very smoothly with just the right amount of resistance to be assured it will stay where you set it. Unlike other variable NDs, this one has orange coloured tabs sticking out that make it easy to turn. It is even labelled, in very small print, to show how much ND it is set to - from 1 to 5 stops. If you are used to how NDs are named in the film production world, this variable ND goes from ND 0.3 to ND 1.5. ND 1.5 in my experience is about as high as we ever use on set. I didn’t realize this until after a few weeks of using this filter, but the “CPL” in the product name actually refers to Circular Polarizer. This is the first and only variable ND I have ever seen that you can also use as a fully-adjustable polarizer filter as well! All variable NDs use two polarizers to darken the image, but the K&F actually lets you rotate the pola independently of the ND setting. Amazing! This variable ND also beats any others I have used because it does not add any colour shift to your image, even at the strongest ND setting, AND it does not suffer from the black cross effect that most other VNDs give you. At $119 Canadian dollars as I write this, it is not an inexpensive filter, but you definitely get what you pay for with optical glass. If you care about image quality, it just does not make sense to put cheap glass in front of your expensive lenses. Very Highly recommended!

K&F are renowned for producing high quality photographic filters and the True Color variable ND (“VND”) with a strength of 2 – 32 (i.e. 1 – 5 stops) filter is no different. I ordered the K&F VND for video work rather than stills photography where having the 1 – 5 stops is perfect for keeping the 180 degree shutter rule when I am out shooting run and gun style. The K&F VND filter negates the need to having to mess around with having to swop out several filters which is ideal for my shooting style. The build quality of the K&F VND is superb. It is made from top quality materials that are well machined and nicely finished. The rotating mechanism is tight enough to stay in place and avoid being moved by accidental knocks but not so tight it is difficult to rotate. In addition, the rotating mechanism is really smooth, which is needed for neat transitions. The K&F VND has a protruding tab, rather than the conventional serrated edges, which makes adjusting this filter super quick and easy. This tab means I can focus on the screen and what I am doing rather than fumbling around trying to change the setting. In my experience all filters affect the image quality to some degree and the K&F VND is no different. The reduction in image quality is minimal when using the K&F VND for video work and it is barely noticeable, even when using the filter at the strongest 5 stop setting. One thing I will say about the K&F VND is that there are no colour casts, at any setting, so the “True color” in the product description is accurate. At £71.99 (at the time of review) the K&F True Color VND filter isn’t cheap, and is actually priced at the higher end of the market. This is to be expected and I think it is always worth to dig a bit deeper for quality filters to maintain the best image quality rather than use cheaper and inferior filters that are going to affect the image quality and potentially render the footage unusable. Using the K&F VND I can shoot with the confidence the image quality of my footage is going to be virtually as good as using no filters at all. Overall, the K&F True Color VND is an excellent filter and one I highly recommend for capturing video footage. It is tough and durable. It is well made and has a smooth action. The protruding tab makes changing settings quick, efficient and fuss free. Okay, it’s on the expensive side but it is definitely worth the extra and very good value for money.

I am happy with this filter, I tried it at home, so far it works well and the colors are fantastic. I will test it well on vacation in Canada. the filter that is needed. Fast shipping as per the manual, really nice leather box and it makes a good impression as a professional. I trusted it...and I am satisfied
