77mm Variable ND Filter ND2-ND400 (1-9 Stops) with Putter HD 28 Multi-Layer Coatings Nano-X Series
SKU: KF01.1465
All reviewers say that the feel of this filter is top notch, but some seem disappointed with the functionality. Maybe I'm just lucky, but the finish and precision is spot on. I've bought two of different sizes and both have great quality and well aligned polarizers (the elements that make it go nighty night), this means that there is no problems with the "cross shadow" (XS). Now, that's a lie! There will always be an XS at some point, but for me this was just before the 8th (last) stop when using it on a wide lense (16mm APSC). Which means that almost the whole range is usable, all that you can ask for with an variable ND filter.

I was surprised by the quality of the filter which is professional and has nothing to say. The materials are good and the glass is great too. The adjustment wheel is very smooth, so you can easily change the density of the filter. You no longer need 4 different filters. Ability to record videos during the largest opening time of the day.

KF products have always been excellent value for money, but these last generations have made an incredible leap in quality. I've been using a predecessor of this filter for years to record video outdoors. This one survived. Good workmanship, splendid presentation in these artificial leather bags that now bring perfect results. The genius lies in the orange control (the seal color of the brand), which makes it easy for us to change the intensity of the ND at any time.

Very useful with a Sony RX10IV to fight against light rays that could spoil photos and videos. Small problem the adjustment is fluid, we would have liked an adjustment by notches. Another problem is that the orange handle prevents the installation of the original sunshield. But you have to choose between a dozen filters and a multi-filter and these two small drawbacks. This brand is always a guarantee of good quality.

The filter is exactly as described,easy to fit, feels well constructed and comes in a sturdy case.As far as I can tell it does not add any innacurate colour cast as some cheap ND filters do.I bought a size to fit my largest Olympus pen f lens( which it does with no problem) and I purchased some low cost lens ring adaptors so that I can use it on any of my lenses(I did the same with a good quality polarising filter).

Quality materials doesn't feel cheap connects to lense super smooth and transitions filter effortlessly but with enough force needed that it won't slip on its own. The raised selector on dial makes it easy to manipulate while running camera without having to search for filter dial. If you are in market for ND filter don't hesitate on this one.

First variable ND filter purchased (all others I have had have been static) and what a difference it makes!
So easy to move around, and not having to carry more than one per lens is a real space-saver in the bag!
I've experienced no false colour or the infamous X on any images (although I don't use this all the way closed!)
Comparing it to a friends premium ND (I won't mention the brand), I could not see a difference at all in image quality. However, the premium ND was a bit stiffer to move around, so it felt like it would stay exactly where left. The K&F one does feel like it may loosen up over time, although this hasn't happened yet a few months in!
