Irix Lens 11mm F/4 Blackstone (Canon)

The Irix 11mm f/4 Blackstone Lens for Canon EF-Mount is an ultra-wide-angle prime designed for full-frame cameras. Its bright f/4 maximum aperture enables working in low-light conditions, and it also benefits working with selective focus and shallow depth of field techniques. The lens' construction incorporates three aspherical elements, two ED elements, and four HR elements to reduce chromatic and spherical aberrations in order to produce a high degree of sharpness and clarity. A Neutrino Coating has also been applied to reduce lens flare and ghosting for improved contrast and color fidelity. A manual focus design with focus lock is employed along with depth of field and focus distance scales for manual focus accuracy and repeatable precision. Additionally, the lens' housing is constructed from weather-sealed magnesium alloy for improved durability and it also sports UV fluorescent engraved markings to help you keep track of focus settings in dim light.
