K&F Concept A-Series MC UV Filter 52mm Ultra-Slim Multi-Coated Protection Filter

With a light transmittance exceeding 99.6% and 16 layers of multi-coating, this 52mm UV filter from K&F Concept's A-Series delivers exceptional clarity while shielding your lens from scratches, dust, and moisture. The ultra-slim aluminum frame prevents vignetting even on wide-angle lenses, and the double-threaded design allows you to stack filters or attach a lens cap without removing the filter.

Overview

The K&F Concept A-Series MC UV Filter is engineered for photographers who demand both protection and optical purity. It features high-quality optical glass with 8 layers of anti-reflective coating on each side, effectively reducing flare and ghosting while absorbing UV light to eliminate bluish casts in outdoor shots. The filter factor of 1 means no exposure compensation is needed, so you can shoot with confidence in any lighting condition.

What stands out

• Ultra-slim aluminum alloy frame (only 3.3mm thick) prevents vignetting on wide-angle lenses.
• Double-threaded design: front threads accept additional filters or a lens cap, rear threads mount securely to the lens.
• Water-repellent and oil-repellent coatings make cleaning effortless and keep the filter clear in adverse weather.
• Scratch-resistant coating protects the glass from everyday wear and tear.
• Multi-coated surfaces reduce reflections to less than 0.4%, ensuring maximum contrast and color fidelity.
