K&F Concept 82mm Variable ND2-ND400 ND Lens Filter (1-9 Stops) for Camera Lens, Adjustable Neutral Density Filter with Microfiber Cleaning Cloth (B-Series)

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!

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!

I purchased this for use on my iPhone 15 pro max for content creation. Videos and photos. This filter is great. I am a newb at photography. But I noticed a difference in photos when taking pictures! If it worked great for my phone. It would work great for an actual camera! Highly recommend!

Just got this but experimented with it on a few photos. Appears to have very good quality for the cost. Make sure you get the 1 size larger lens cover (see the manuf. web site for details).

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!

The media could not be loaded. The quality is high, everything works well. What I didn’t like is that it’s not intuitive to tell the filter’s intensity - you have to figure out where it should align each time and roughly guess which filter is currently on. But I think you can get used to that. Maybe I was just unlucky, but it was really hard to unscrew it after installation. The worst part was the lens case - it’s extremely difficult to open, even if you have nails.

Works great! Definitely recommend!

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
