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)

I've been very impressed with this item for the past 2ish years. It's been a durable design at a very affordable price. It fulfills everything that it said it would and is easy to install and use. My images are still very clear and not cloudy as I use the filter.It makes a huge difference in my image using this filter to help reduce the harsh light coming into my camera. There is a slight vignette on the image, but not drastically noticeable.The only downside is the lack of gauges to keep track of what stop the filter is at. It requires you to watch the LCD screen as you turn the knob on the filter. Still happy with the product, but wish there were numbers on the filter. Overall, highly recommend, especially for the price!

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 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!

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.

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!

I love this article, it was very helpful, I would like a collaboration with you 😍

I ordered this as a new product. What I received was clearly a returned item. It does not look to be damaged or heavily used so I will continue with an evaluation. It just seems that if returns are going to be sent out, the items should be identified as such.
