I recently tried out the 52mm Clip-on ND2-400 Phone Camera Lens Filter by K&F Concept, and it's transformed my phone photography experience. This versatile filter offers a wide range of light reduction options from ND2 to ND400, allowing for creative control over exposure in various lighting conditions.

The clip-on design makes it compatible with a range of smartphones, including the latest iPhone models, ensuring that I can achieve professional-quality results with my mobile photography. Whether I'm capturing landscapes, portraits, or action shots, this filter helps me achieve the perfect balance of light and shadow.

Overall, I highly recommend the 52mm Clip-on ND2-400 Phone Camera Lens Filter to any smartphone photographer looking to elevate their images. It's a compact and convenient accessory that delivers impressive results, making it a must-have for mobile photography enthusiasts.

Great product! Better build quality than my Tiffen, and no nasty color cast.

52mm ND2-ND32 (1-5 Stop) Variable ND Filter and CPL Circular Polarizing Filter 2 in 1 for Camera Lens. What can I say? Unusual. Being able to adjust the ND filter and polarization at the same time without swapping the filters is super handy. Quick adjustments can make all the difference between getting the perfect shot in the moment or the perfect video pan. I have a Sony ZV-1 with a 52mm adapter for the lens and it threads in seamlessly and smoothly with no issues. Although my camera is equipped with a built-in ND filter. The K&F goes even further by having more control over how much light my camera picks up. The polarization aspect of the K&F further enhances the image quality.

I have been looking for a CL/ND combo 52mm filter for my iPhone 11. This one is excellent and the right one to use on overcast days, or in bright interiors when I need to keep the shutter down to 1/48 and don't want high lights to blow out.

These is my 2nd variable ND from K&F. The quality it's good as Tiffen and others manufacturers. Instead of have a lot of ND of different sizes it's better have a variable ND for my photography work and save same money.

The only CONS it's the protective case that came with the ND. It's nice but too big.

While they are not B&W or even Tiffen, I do like K&F Concept filters. Their filters tend to be well made, have a minimum of distortion and colorization especially considering their reasonable price. The 52mm Nano-X Black Soft Filter is another example of a well made, inexpensive filter.

Keep in mind that this is a special effects filter. It won’t be much value in normal, everyday photography. It is a Diffusion Effect filter. These filters were very popular in Hollywood films especially in the 1940s and 1950s. The were used for reducing blemishes and wrinkles on actor’s faces (especially on women) and for creating glowing effects. However, if you need or want these kinds of effects in your images, the K&F Concept 52mm Nano-X Black Soft Filter will do the job at a reasonable cost.

I have both a tiffen vari ND and this one. And I like this one even better! My tiff filter has a slight bluish tint and it doesn't even turn too far. I also like that it has a hard stop and therefore doesn't have any x patterns. Quite the opposite of meeting.

In addition, the k&f filter can filter out almost 1 1/2 stops more light than the tiffen, without a vignette.
If I hadn't already bought the Tiffen I wouldn't have it in my camera bag anymore. So he lies around and is no longer used.
