K&F has risen to the top when it comes to choosing filters for my cameras. They produce products at various price points while delivering excellent value and performance. This filter is no exception. Minimal color shift with no other visible artifacts (X). Smooth rotation through the stop range (no clicks). Given the cost of this filter, this is an excellent value.

have and reviewed a few Neutral density filters. They are one of my favorite tools to use in landscape photography. This will be my first Variable ND experience. I'm familiar with K&F so it was a no brainer to give it try. I'm looking to improve my odds of getting dramatic skies on days that are very overcast or hazy. My camera has Aperture, ISO and shutter speed that unfortunately don't impact the hazy and overcast cloud cover situations. This filter will be a 4th way to control the light, and that by dimming select portions of the light simply by rotating the dial. When set up, we will be essentially changing the light coming from the cloud part of the frame but leaving the rest of the light details unchanged. Thats the high level view of what this does. It functions by turning an element on the front of the lens that will let you see which areas are being affected. In Use like other K&F products, they include a sturdy case to keep the optics fingerprint and smudge free. This particular kit includes 3 free microfiber cleaning cloths, individually wrapped. The few days I went out with this it was cloudy but not hazy or overcast. Still, the filter brought out more detail in the clouds and made them a tad less exposed Improving the overall shot. I will continue to use these confident that under the overcast skies I'm going to bring out more cloud sharpness and definition and cut through the haze. So Far so good.

This variable density filter is ease to use and keeps decent color balance. Essential lens for your kit. Recommeded.

Perfect for what I needed

This is surprisingly good. Allows exposures of several seconds in bright sunlight at its maximum setting which came in handy for a recent trip to the coast. There’s a slight cast, but nothing that can’t be warmed up in lightroom. Happy to recommend

Just good

This filter is perfect on my Fuji lens. A simple twist releases the Magic, and adjusts the amount of light that can enter the lens. This allows easy long-exposure shots, and lets you get more creative with your photography. A simple easy fit, it feels good quality too, being made of quality materials. I've used K&F Concept products before, and have found them to be good and reliable.

Works well. I use a canon r100 with a 18 to 150 lense. Awesome pics with this adjustable filter. Highly recommend.

The adjustable range from gives me so much flexibility, allowing me to easily control the light in different settings without having to switch filters. It’s slim, so it doesn’t add bulk to my camera, and it doesn’t cause any vignetting, even at wider angles. The true colour quality is impressive, with no colour shift, so my photos come out looking natural and vibrant. It’s also very smooth to adjust, making it easy to set the exact level of light reduction I need.

took the opportunity to test an ND filter from K&F, as I've been very satisfied with most of their products so far. ND filters are particularly useful for darkening fast lenses in strong sunlight without drastically reducing the shutter speed or closing the aperture—and thus losing the desired bokeh. I was pleasantly surprised by the filter. The brightness can be continuously adjusted by simply turning it—a huge advantage. Since this is a cheaper option, there's no magnetic function, for example, where the filter can be easily removed if it's not needed for a short time. Only the screw-on ring remains on the lens. I missed that in this version. K&F's high-quality workmanship and well-thought-out packaging convinced me. However, I would personally opt for a cheaper alternative, as I rarely need the filter for my video recordings. However, it's a great option for occasional use. Note on the Vine program: I received this product for free as part of the Vine program. I only test products I actually need and rate them honestly based on my own experience.
