Irix 11mm f/4 Firefly Lens for Canon EF (USED)
The Irix 11mm f/4 Firefly Lens for Canon EF is an ultra-wide prime lens engineered to provide an expansive, rectilinear field of view for full-frame digital SLRs. Delivering an incredible 126-degree diagonal angle of view with minimal distortion, this lens is ideal for landscape photography, architectural shots, interior imagery, and astrophotography. Built with a lightweight, weather-sealed Firefly housing, it combines sophisticated optical performance with rugged dependability in the field.
Advanced Optical Construction
Engineered with an optical layout featuring 16 elements in 11 groups, the Irix 11mm f/4 incorporates four high-refractive index (HR) elements, two extra-low dispersion (ED) elements, and three aspherical (ASP) elements. This sophisticated arrangement actively suppresses chromatic aberrations, spherical distortion, and coma, ensuring high edge-to-edge sharpness and clarity even at maximum aperture.
Precision Manual Focus Features
Designed specifically for precise manual focusing, this lens features an ergonomic focus ring with an audible "click" at the infinity position, allowing for fast and accurate setup in dark or low-light conditions. The Focus Lock ring enables shooters to lock the focusing scale at a specific distance to avoid accidental movement during extended time-lapses or night sky shoots.
Durable Weather-Sealed Design
The Firefly version of the Irix 11mm f/4 features a lightweight plastic housing reinforced with an anti-slip rubber focusing ring for enhanced tactile control. Internal rubber seals protect the optical assembly against dust and moisture, ensuring reliable operation when shooting outdoors in unpredictable weather conditions.
