Everything about this KF filter projects quality and precision including the packaging. The filter comes in a sturdy reusable box featuring a slide in/out drawer with a cloth tab handle. Pulling on the cloth handle reveals a tan and thick leather case with a magnetic closure. But there’s more. On the side of the leather case is another cloth tab and when it’s pulled it gently slides the filter out from inside the wallet so no fingers are needed.

Lifting up the filter, the first thing I noticed was the weight. The 77mm size I’m using weighs 4.4 ounces. The trade-off though is precise smooth, fluid-like control. Two gold anodized handles are conveniently located opposite each other and rotating them can adjust both the ND filter and/or the polarizer filter. It takes a little time to learn to use it since it's a dual function setup. Once the filter is screwed onto the lens, the inner dial which adjusts the polarizer can turn a full 360 degrees just as a typical polarizer. The outer ring can rotate about 40 degrees and adjusts the ND filter from 2 to 32 stops.

It's important to adjust the polarizer so as not to produce unnatural dark and light areas in your sky, unless that's the effect you want. (See photos) Of course you can also dial in no polarizing effect at all. The filter turns smoothly and precisely and I appreciate the large handles on the dial so I can concentrate on the photo. The knobs do prevent use of sunshades on my lens so sun glare will be an issue at times.

Bottom Line: I really appreciate no being limited to selected ND ranges but I can dial in any amount of light control from ND 2 to 32, plus polarization. The storage case makes for easy retrieval in your camera bag. One interesting note is that there are directions included for turning the shipping box into a picture frame. I purchased the 77 mm filter and I'll need to purchase an additional 80mm lens cap if I want to protect the front. High quality filter combo that provides convenience and a great latitude of light control. Photos provided are to demonstrate filter effects.
