Offering a wide-angle perspective, and characterized by its premium exterior build, the 15mm f/2.4 Blackstone Lens from Irix is a sophisticated prime lens designed for Canon EF-mount cameras. Benefitting the broad field of view is an advanced optical design that features aspherical, low-dispersion, and high-refractive index glass elements to control various aberrations and distortions, as well as maintain accurate and consistent color. A Neutrino coating is also utilized to control lens flare and ghosting and achieve a high degree of contrast and color fidelity when working in strong lighting conditions.
Complementing the optics, this 15mm f/2.4 makes use of a manual focus design for fine-tuned control, and incorporates a unique positive focus lock to secure the focusing position at any point for consistent, repeatable shooting. As the Blackstone version of this focal length, this lens is also distinguished by an aluminum and magnesium alloy exterior, engraved lens markings with fluorescent UV paint for high visibility, and extensive weather-sealing about the lens to permit working in harsh environments.
The Blackstone version of the 15mm f/2.4 lens features a durable aluminum and magnesium alloy housing and weather-resistant exterior along with inner seals, and an extra seal at the front element, to protect against dust and moisture intrusion. The metal exterior also distinguishes itself with an anti-scratch finish, and sports engraved focus distance and depth of field scales with fluorescent UV paint for high visibility when working in low-light conditions.
