Designed for cine-style image capture and covering up to full-frame size sensors, the black Leica L-mount 45mm T1.5 Cine Lens from IRIX incorporates multiple internal and external design features. External features include a 95mm front diameter, 0.8 MOD gears, luminous focus marks in feet, and a detachable 1/4"-20 support foot. Internally, nine blades produce smooth, rounded bokeh, and five seals protect against inclement weather and dust.

To help eliminate aberrations and distortion, the IRIX 45mm T1.5 Cine Lens is constructed with 11 optical elements in nine groups, including four HR (high refractive index) and three ED (extra-low dispersion) elements. This lens has 180° of focus and 75° of iris rotation and incorporates an 86mm front filter thread.
