Well i have to say K&F have smashed it out the park with this new filter system, i am yet to see how well it stands up against its rivals, but for design and feel thi sis remarkable.. It have it all, and easy mount to lens, with lock. It has the easiest CPL mount with a massize easy to use spin wheel, the filter have a good plastic edging to help damage and fingerprints, and the large thumb and finger grip to put the filter in the mount are so good even with gloves on.. I have to say i am very impressed.. Oh and not only that its all in its own leather case..

I use the filter both for filming with the DSLR, as well as for long-term exposure during the day with an open aperture, especially when filming, it is simply beautiful with an open aperture. The ring is easy to turn. However, sound should be recorded externally, because the ring clicks quietly in the intended positions. The packaging is ideal for transport and also withstands the attacks of my 1-year-old daughter. The picture quality looks great. In any case, I could not see any color casts or other disturbances. I am very satisfied with the ND filter.

The filter looks valuable and the packaging is good. Unfortunately, my copy showed clear vignettes in both the direction of ND32 and ND2, making the filter virtually unusable. In addition, the minimum stop was not clean, so that a clear darkening was already visible at minimum (>ND2), only turned a little further did I actually have ND2. So it went from slightly darkened (>ND2) to bright (ND2) to significantly darkened (ND32). It's a shame, but that's why I sent the filter back. I then did not examine the glass quality more closely.

The filter comes in a very elegant packaging with a magnetic closure and also has a small plastic box for transport. The filter can be easily screwed on and off the lens , estimated at the maximum setting 3-4 full f-stops. You can see the effect best in backlight or strong contrasts in the subject, I'm looking forward to testing the filter in the midday sun in summer.

Works great if you're starting out with long exposure photography, but has a bit of vignetting and color cast
