K&F Concept 67mm Variable ND2-ND400 ND Lens Filter (1-9 Stops) for Camera Lens Adjustable Neutral Density Filter with Microfiber Cleaning Cloth (B-Series)

The K&F Concept 67mm Variable ND2-ND400 Filter is an outstanding addition to my camera gear! It provides excellent control over exposure, allowing me to shoot in bright conditions while maintaining proper image quality. The filter is well-built, easy to adjust, and produces smooth, even results without any noticeable color shifts. Whether you’re a photographer or videographer, this filter is a must-have for achieving great shots in varying light conditions. Highly recommend!

This ND filter is a fantastic addition to my photography gear! Made from high-quality AGC optical glass with 8 multi-layer coatings, it really reduces reflections and glare, resulting in crystal-clear images. The 1-9 stop light adjustment is incredibly versatile, perfect for everything from bright daylight shots to more controlled, low-light scenes. The 360-degree rotation offers precise control over the light reduction, although, at the highest stops, I did notice a faint cross-pattern ("X" effect), which is typical for adjustable ND filters on some lenses.The filter itself is sleek and slim, just 7.4mm thick, and the CNC-patterned edge provides great grip, making it super easy to attach or adjust quickly. I love the anti-glare finish, which minimizes stray reflections, especially in challenging lighting. One thing to note: you’ll need a 55mm lens cap for this 52mm filter, but that’s easy to work around.Overall, it’s an impressive ND filter with outstanding performance and durability. Highly recommend it to anyone looking to improve their outdoor and landscape photography!

First off let's say that this ND filter offers visual quality compared to the more higher priced ND filters. It punches above its weight and class on clarity and lens protection as well. I have dropped this by mistake twice and the filter has held up to the impact of falling on it side and face. It does not have any cracks and still works as it should. The mounting system locks up and adheres to the front of the lens without having to over tighten it with fear of losing it. It shines and performed the most on sunny days when you want the most subject separation. However it does not offer any polarization.

I love this variable filter that I use on my Nikon D5600 DSLR. I’m an amateur photographer, kind a “B-minus” student on the technical side of things. But, I do enjoy, and am getting fairly good at, various long-exposure techniques including ICM, which can lead to blown-out/too brightly-exposed sunny outdoor shots. Learned about ND filters in my photography class. Apparently, you can take your shutter speed and aperture settings and pump them through an algorithm to determine where to set your ND filter, or which non-variable filter to use. Too complicated for me. When I set my exposure length and aperture settings with the ND filter at its “Min” setting, then point my camera at a sunlit subject, my camera will flash “Subject Too Bright”. I just start slowly rotating the variable ND filter’s ring toward “Max”. As soon as that “Subject Too Bright” message goes away, I know it’s OK to release the shutter. Perfectly exposed shot every time with this inexpensive variable ND filter.

Came early then expected ( : nice and snug on my Sony a7 iii will be using for motorsport photography etc no streaking with they micro fiber cloth. Will update photos next event I attend. The build quality for they price surpassed my expectations. 72 mm f4 70-200

This is the coolest filter I have ever purchased for a camera. Okay, so it's not magic, but to be honest it might as well be. I have no clue how it works but it is the smoothest transition from each level. It goes from barely there to extremely dark in a smooth transition just by slowly turning the dial. Way cool, practical and perfect! Image quality through it is great. Don't hesitate to buy this. Also, fyi, you can buy a OEM cap to fit it. The listing has the lens cap size in the description so I ordered a lumix cap in that size and it fits perfectly. You will want one so you can leave the filter on without issue.Also, a word of CAUTION!! Don't put this on with an auto close cap!!! It jacked my camera up and I was afraid it was gonna be wrecked. Took some finagling but I finally got the filter off and restarted camera and it fixed the error. But it was scary!! So be sure to have the auto cap removed before using! These filters do not work with an auto cap!

Great product! It doesn't create vignette if you go high number on filter

For the price it’s amazing and it does its job I just can use the darkest ND setting because of the X marker but I can just try to up my shutter speed instead at that point. Over all it’s not bad I just wish I didn’t get the huge X. I shot with r6 mark 2 24-70mm 2.8
