## Long description

The Irix Blackstone 11mm f/4.0 is an ultra-wide rectilinear lens for SLR cameras, offering a 126° angle of view and a compact, robust aluminium and magnesium body. With 16 elements in 10 groups, including high-refractive, ED and aspherical elements, the lens delivers high image quality with minimal distortion while remaining lightweight and portable. It is compatible with Canon EF mount and designed for landscape, architecture and on-the-go photography where wide coverage and durability are required.
Advantages
This 11mm f/4.0 lens provides an extremely wide field of view combined with rectilinear rendering, keeping straight lines accurate with distortion as low as 3.13%. Optical construction includes 4 high-refractive elements, 2 ED elements and 3 aspherical elements to reduce aberrations and preserve image sharpness across the frame. The aluminium-magnesium body offers solid mechanical protection, and the ergonomically rubber-coated, anti-slip focus ring improves handling. Weather sealing and inner seals protect the lens against dust, moisture and incidental splashes. Despite its durable construction, the lens weighs approximately 0.79 kg, making it a lighter option for travel and field use.
