Cokin 52UVS 52mm Pure Harmonie Ultra Slim UV Filter

The Cokin 52UVS Pure Harmonie Ultra Slim UV filter addresses a common frustration among photographers: standard UV filters that add bulk, cause vignetting on wide-angle lenses, and degrade image quality. At just 3.3mm thick, this filter sits nearly flush against the front of your lens, making it one of the slimmest UV protection filters on the market. The ultra-thin design is particularly valuable for photographers shooting with wide-angle or ultra-wide-angle lenses, where thicker filter rings can intrude into the frame and produce dark corners.

Beyond its slim profile, the filter features Cokin's EVERCLEAR 5 coating technology, a five-layer treatment that repels water, oil, dust, and soil while adding scratch resistance to the glass surface. This multi-coating also reduces reflections and maintains high light transmission, ensuring that the filter functions as a transparent protective barrier rather than an optical compromise. For photographers who prefer to keep a UV filter on their lens at all times as a first line of defense against dust, moisture, and accidental contact, the Pure Harmonie offers that protection without the usual trade-offs in image quality or compatibility with wide-angle focal lengths.
