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. This filter is said to be explosive-proof.. I am not 100% sure if that means the filter won't explode when dropped or if it is impact resistant and will take the brunt of the force? The instructions/information allude to both cases so I'll just roll with that! From time to time I do find myself in or around areas where things might get a little dicey.. I shoot in industrial areas where debris might get airborne, and I shoot sports where things have come hurling towards me/my cameras, and when I shoot F1 or other high speed auto events there is always flying debris along the track. All that said, I can absolutely see a use case for this type of protection! The filter itself is extremely well made and machined to perfection. I have yet to find ANY defects in my growing collection of K&F Concepts kit. The filter screwed right on to my Canon EF 70-200 f/2.8 IS USM III with ease. Very satisfying... NOTE: Never over tighten filters! Once on my camera, I took a few test shots (with and without the UV filter) and there was no discernible differences in the images. I took pics in strong/direct light, diffused light, and at dusk and again no issues at all. No haloing, no vignetting, no streaking, no bright/dull spots. Everything was just fine! The description says that 98.9% of light is transmitted through the filter which I absolutely believe to be true.
