Product Description

The IRIX 15mm f/2.4 is an ultra-wide prime lens designed for full-frame Canon EF-mount cameras, offering an expansive field of view that’s perfect for landscapes, architecture, and astrophotography. With its fast f/2.4 aperture and a sweeping 110° angle of view, it’s well-suited for capturing dramatic scenes with strong depth and perspective. The optical design incorporates a mix of aspherical, extra-low dispersion, and high-refractive elements to keep distortion and chromatic aberrations well controlled while maintaining sharpness from edge to edge.
This is a fully manual focus lens, built with precision in mind. It features a long, smooth focus throw along with a focus lock mechanism, making it especially useful for critical work like astrophotography or hyperfocal shooting. The lens is also weather-sealed, adding durability for outdoor use, and includes both a front 95mm filter thread and a rear gel filter slot—giving you flexibility when working in bright or challenging lighting conditions. Despite its wide field of view, it maintains a solid, well-balanced feel on DSLR bodies.
