Grade 010 with Filter Factor 0 (Zero) - The filter does not reduce light reaching the sensor, preserving exposure, color, and contrast. Rugged construction and materials - Metal filter ring with a black finish provides durable, field ready mounting. - Heat treated glass offers enhanced strength and long term reliability in challenging environments. Slim design for clear framing - Slim profile minimizes vignetting, helping maintain full image coverage even with tighter frame compositions. Key benefits - Maintains exposure: zero filter factor means no change to shutter speed or ISO requirements. - Durable build: metal ring and heat treated glass designed for repeated use and travel. - Clean optics: slim design reduces the risk of corner shading on constrained frames. Usage scenarios - Landscape photography on bright days where maintaining exposure accuracy is important. - Architectural shots with high contrast scenes where clarity and integrity of edges matter. - On location shoots with wide or tight framing where a slim filter profile helps prevent vignetting while preserving image quality.
