Product Overview
I recently had the opportunity to try out the K F Concept Variable ND Filter, and I must say that I was pleasantly surprised. This filter is designed to reduce reflection from the filter itself and glare, ensuring high quality images in a variety of scenarios. It features an ultra slim frame that is only 7.4 mm thick, so it can be used with 16mm telephoto and wide angle lenses without vignetting. Additionally, it has hydrophobic, oil proof and scratch resistant coatings on both sides of the filter glass for protection against wear and tear during outdoor use.
The K F Concept Variable ND Filter is made with imported Japanese AGC optical glass and 28 multi layer coatings for superior image quality. It also features a putter design which allows you to accurately adjust the stop for video shooting. Each stop from ND2 to ND400 is marked on the frame for easy adjustment via 360 degree rotation. The filter fits all 82mm lenses, so you don t have to worry about compatibility.

In my experience, the K F Concept Variable ND Filter was quite easy to use and produced great results in a variety of scenarios. The picture quality was excellent and I didn t notice any vignetting even when using wide angle lenses. The filter s putter design made it very easy to adjust the stop and I was able to get consistent results every time. The multi layer coating also ensured that there was no glare or reflection from the filter itself, resulting in clear images with accurate colors.
Overall, I would highly recommend the K F Concept Variable ND Filter for anyone who needs a reliable filter for their camera setup. Whether you are a professional photographer or just starting out, this is an excellent option that will produce great results in a variety of scenarios. It is well built with high quality materials, so you can be sure that it will last for many years to come. Plus, its competitive price makes it an even more attractive option.
