Small kit including an 82mm UV filter, an 82mm lens cap and a small elastic band for the lens cap. When I go for a photo walk with friends in the countryside/forest, between branches that can come back in boomerang, brambles and other thorny vegetation or just dust, tree resin or other, as an amateur who does not necessarily have the means/desire to insure or especially replace his equipment, I appreciate knowing that the front lens of my lens is protected. Whether on my 30 Mpx camera or the 24 Mpx camera, even with my pricked Laowa Macro 100mm, in 95% of cases there is no significant visual impairment between with and without the filter. Of course, for landscape, portrait or studio shots as a professional with much more expensive equipment, my point of view would have been different. But as an amateur, the negligible impact on sharpness is largely offset by the increased protection. The lens cap is also more than welcome, classic plastic construction, very good. Even though the original lens cap fits on the filter too, the cap is suitable for creative filters with a support ring on lenses of different diameters. I can't imagine using the little strap, at least not to keep the lens cap from dangling on the lens itself. I find that even more annoying than anything else about the lens cap. For €18.40 at the time of testing, the kit is very good.
