Product Overview
I recently purchased the K F Concept Variable ND Filter ND2 ND400 1 9 Stops . I had been looking for a filter that could provide me with maximum flexibility while still being durable enough to withstand my outdoor adventures. After extensive research, I decided to give this product a try. In this review, I will outline my experience using this filter and provide my thoughts on its features and performance.
To begin, the quality of the material used in this filter is top notch. It is made from imported Japanese AGC optical glass and has a total of 28 multi layer coatings. This ensures that the image quality is very good and that reflections and glare are effectively reduced. Additionally, both sides of the filter have been treated with a multi layer hydrophobic, oil proof, and scratch resistant coating which makes it suitable for outdoor use. The frame is also very slim at only 7.4mm thick which prevents any vignetting when used with wide angle lenses.
In terms of its performance, I found the K F Concept Variable ND Filter to be excellent for landscape photography. The adjustable stops from ND2 to ND400 allow you to perfectly dial in the amount of light you need for your shot without having to change filters or adjust your settings manually each time. Additionally, the filter frame has been designed as a putter which makes it very easy to adjust the stops accurately this is especially useful if you re using video shooting tools or auxiliary tools as you can easily adjust them without having to take your eye away from your subject.

Overall, I was highly impressed with this product s performance and features. The build quality is excellent and it offers great flexibility in terms of its adjustable stop range from ND2 to ND400. It s also very easy to use thanks to its putter design which makes adjusting your settings an effortless task as well as its slim frame which prevents any vignetting when used with wide angle lenses.
In conclusion, I would highly recommend the K F Concept Variable ND Filter ND2 ND400 1 9 Stops for anyone looking for a high quality filter that offers great flexibility while still being durable enough for outdoor use. Its adjustable stop range allows you to easily adjust your settings without having to change filters or make manual adjustments each time its slim frame prevents any vignetting when used with wide angle lenses and its hydrophobic and scratch resistant coating means that it s suitable for outdoor use even in harsh conditions. All in all, this is an excellent product that I would definitely recommend trying out!
