I have come to rely heavily on K&F Concept filters and wares. Their quality is excellent and, as with this lens filter, are definitely forward thinking/looking in their product offerings.

The 77mm filter I received is super cool.. mating up a circular polarizer (CPL) and a 1/2 black mist filter to deliver some softened dreamy images! The result of the filter is on the more subtle side softening some details and features. You will lose sharpness in your images but that's sort of the point..

The CPL is excellent and easy to use - spin the rotating portion of the filter to get the desired effect. The filter ring is manufactured in such a way. that turning the filter is effortless and easy on your hands (doesn't feel like you're spinning a hacksaw!). Installation is a breeze - the machined screw bezel is perfect and screws on oh so smooth!

NOTE: Do not over tighten filters!

The images would be great for senior portraits or even environmental portraits. I wouldn't use for a lot of commercial work as they typically want everything (at least the subject) to be tack sharp... but for some of my freelance or more creative work this filter will be a huge hit!
