Impressive, High-Quality Filter
The discussion continues as to the need to keep a clear filter mounted, mostly to protect your lens. But I definitely keep one on each lens. I'm impressed with this K&F filter. It is very lightweight. The ring holder for the glass filter is metal and well-machined. One of the features I really like is the fact that they have incorporated a couple of reeded sections on the outside of the ring. Sometimes filters can get stuck and be difficult to remove, and those serrations help get a good grip for unscrewing. The ring itself is very thin—I measured it at 6mm, including the threads. The thinner a filter is, the less likely it is to be visible in your shots, especially when using very wide-angle lenses. I don't know what kind of coatings they have used on the glass—stated as 28 layers in the ad—but the reflection color is a yellowish-green, as opposed to the more bluish-green I've seen on many other filters.
