Irix 11mm F4

The Irix 11mm F4 is an ultra wide-angle manual focus prime lens designed for full-frame DSLR cameras, available in Canon EF, Nikon F, and Pentax K mounts. With a 126° angle of view, it's ideal for capturing expansive landscapes, architectural structures, and interior spaces. The optical design includes four high refractive index elements, two extra-low dispersion elements, and three aspherical elements to minimize distortion and aberrations, delivering sharp and accurate images.

Both versions feature weather sealing to protect against dust and moisture, ensuring reliability in various shooting conditions.
