Cokin 43UVS Pure Harmonie Ultra Slim UV Filter

The Cokin 43mm Pure Harmonie Ultra Slim UV-MC Filter brings the same precision engineering found in the larger Pure Harmonie line to the 43mm filter thread size. At just 3.3mm thick, it is purpose-built for compact mirrorless and rangefinder lenses where every millimeter of added bulk matters. The exclusive high-transmission glass ensures that sharpness, contrast, and color accuracy remain unaffected, making it a practical choice as a permanent lens protector that stays on through every shoot.

Cokin's EVERCLEAR 5 coating technology sets this filter apart from basic UV options. The five-layer treatment provides water repellency, oil resistance, anti-dust, anti-soil, and scratch-resistant properties, which means the filter stays cleaner longer and is easier to wipe down in the field. The ultra-slim profile also reduces vignetting concerns if your 43mm lens happens to be a wide-angle optic. For photographers who want hassle-free, high-quality lens protection on their smaller-threaded lenses, this filter delivers without compromise.
