Perfect protection and high light transmission in Irix Edge UV & Protector filter
This ultra-slim UV filter offers extraordinary light transmission thanks to the high quality optical glass and multi-layer antireflective coating. It’s additional waterproof NANO coating helps keeping the glass surface free of stains and water droplets. Irix UV filter also provides decent protection of the front lens under extreme circumstances. Irix UV filter has been designed especially for Irix 15mm f/2.4 lens. It’s low-profile frame and knurled edges provide very good grip. The additional waterproof coating helps keeping the glass surface free of water droplets under rainy weather.
Reducing the reflections with Irix Edge Circular Polarizer filter
Irix Edge Circular Polarizer (CPL) filter reduces reflections from non-metallic surfaces, emphasizes details and increases colour density of the pictures. Thanks to the slim and ultralight aluminium frame with knurled edges, filter is easy to operate through filter window and causes no vignetting on Irix 15mm f/2.4. The glass surfaces of Irix polarizer are covered by multi-coated antireflection layer that keeps the image clear and full of natural colors.
Diversion of long exposure photography thanks to Irix Edge Neutral Density filters
Irix Edge Neutral Density filters (ND) are an essential tool for long exposure photography and depth of field’s manipulation. They reduce the light that is passing through the lens by 3-stops (3EV), 5-stops (5EV), 7-stops (7EV) or 10-stops (10EV) and help creating astonishing and surreal images. Their additional waterproof and oil repellent NANO coating prevents from stains, fingerprints and enable using in extreme weather conditions.
