Irix Cine-objectief 21mm T1.5 Canon RF-mount - metrische schaal, full-frame cinema prime

Experience ultra-wide cinematic perspective with the Irix Cine Lens 21mm T1.5 for Canon RF mount. This full-frame prime lens delivers exceptional optical performance with a fast T1.5 aperture, ideal for low-light shooting and shallow depth-of-field control. The precise manual focus design features a 180° focus ring rotation and industry-standard 0.8 MOD gears for seamless follow focus integration.

Advantages

The advanced optical design incorporates 11 elements in 10 groups, including 4 high-refractive (HR) elements, 2 extra-low dispersion (ED) elements, and 1 aspherical element. This sophisticated construction minimizes chromatic aberration, distortion, and flare, ensuring sharp, high-contrast images across the entire full-frame sensor. The 11-blade rounded iris produces smooth, cinematic bokeh, while the T1.5 to T16 aperture range offers extensive exposure control. Weather sealing with 3 rubber seals protects against dust and moisture.
