A quality filter that delivers on its promises.
My 135mm and 40mm Sigma Art lenses are extremely sharp. Some would say clinically sharp, maybe too sharp for portraits. My personal experience has been that’s not always the case, but I sometimes find myself wishing I could dial them back slightly. This K&F Concept Black Diffusion 1/4 filter does just that, almost like magic.
The effect is subtly-different from applying a similar effect in software. I like that the effect with the filter on the lens is noticeable, but without being too obvious. It’s an excellent compromise that seems to work well for me. Deciding precisely when to use this filter will be an ongoing learning experience that I’m looking forward to.
One thing worth noting is that the effect when on the 135mm lens is not exactly the same as when on the 40mm lens. That might be one reason for the different strength options.
Physically, there’s a lot to like. Construction is solid, the fit is precise and the coating is doing its job. A solid five stars for function, quality and value at the current price.
