Product Overview

I recently had the pleasure of trying out the K F Concept Variable ND Lens Filter. This product has quickly become one of my favorites, and Im sure it will be a favorite for many photographers and videographers.

The Variable ND Lens Filter is made with high grade Japanese AGC optical glass, and it has 28 multi layer coatings to reduce reflections and glare. This ensures that the image quality is always top notch. The filter also features a putter adjustable design which makes it easy to accurately adjust the stop for different types of photography or video shooting. I found this feature to be incredibly useful, especially when using different lenses and focal lengths.

The Variable ND Lens Filter also comes with a waterproof and scratch resistant coating on both sides of the filter. This ensures that it can handle any type of weather or environment without being damaged in any way. Additionally, the filter has an ultra slim frame 7.4mm which allows for no vignetting when using wide angle or telephoto lenses.

Finally, this product is compatible with all 77mm lenses, so you dont have to worry about compatibility issues when purchasing this filter. One thing to note is that due to the difference in lens type and focal length, you may experience dark X cross in some photos or videos however, this can easily be fixed by rotating the filter slightly until it disappears.

Overall, I was very impressed with the K F Concept Variable ND Lens Filter and I would highly recommend it to anyone looking for a good quality filter for their photography or video needs. Its a great product that offers excellent image quality and plenty of features that make it easy to use in any situation. If youre looking for a reliable variable ND lens filter, this is definitely worth considering!
