A well machined and optically made filter
This K&F Concept Slim Variable ND Neutral Density Filter comes in presentation type cardboard box (handy for gifting) with the actual filter inside protected by a plastic ‘clam-shell’ type storage /carry case. It’s also complimented by three cleaning cloths. I chose the 77mm filter thread size and is graded as being true colour ND2-400. The machining is first class with a very well precise thread that slides effortlessly on my Canon 17-40mm lens. The adjustable control is a joy to use as the turning action is nice and crisp and does the job of fading out unwanted light. The actual degrees are marked -etched on the rim of the filter in white and using ‘live view’ makes it easy to see the change as you twist the element and certainly helps eliminate blur in some of my photos.
