Cokin 52UVS 52mm Pure Harmonie Ultra Slim UV Filter

The Cokin 52UVS Pure Harmonie Ultra Slim UV filter is engineered for photographers who want reliable lens protection without any compromise in optical performance. At just 3.3mm thick, it is among the thinnest UV filters on the market, a design choice that directly addresses the vignetting problems that plague thicker filters on wide-angle lenses. The filter uses exclusive high transmission glass that allows maximum light throughput, so it can remain on the lens as a permanent protective element without affecting exposure or color rendition.

The EVERCLEAR 5 coating technology applies five distinct protective layers to the glass surface: water repellent, anti-oil, anti-dust, anti-soil, and scratch resistant treatments. This multi-coating not only reduces lens flare and ghosting but also makes the filter far easier to clean in the field. The lightweight construction ensures the filter adds virtually no weight to the lens assembly, preserving autofocus speed and overall handling. For photographers seeking a set-it-and-forget-it protective filter that stays out of the way optically, the Pure Harmonie represents a well-considered balance of protection, clarity, and minimal physical footprint.
