The Irix Cine 45mm T1.5 Micro Four Thirds lens brings a natural perspective, fast light transmission, and cinema-focused manual control to Micro Four Thirds production. Its 45 mm focal length is paired with T1.5 transmission and 43.3 mm full-frame image coverage, giving filmmakers an optical design that can serve multiple sensor formats, while this version mounts directly to compatible Micro Four Thirds cameras. The imperial focus scale is marked in feet for crews that work with feet-based distance references.
Detailed Optics with Controlled Focus Changes
The optical system uses 11 elements in 9 groups, including 4 high refraction elements, 1 low dispersion element, and 1 aspherical element. Irix rates the lens for Ultra HD 8K capture. Internal focusing supports consistent handling, while very low focus breathing helps reduce visible framing shifts during focus changes. A 9-blade rounded iris provides smooth background blur and continuous adjustment from T1.5 to T22.
Built for Cinema Accessories and Manual Control
The focus ring rotates 180 degrees, and the aperture ring rotates 75 degrees. Both use 0.8 M gear pitch for integration with compatible cinema control systems. The lens also provides an 86 mm front filter thread and a standardized 95 mm front diameter for compatible accessories. Irix MMS compatibility supports rapid use of matching magnetic accessories, while the adaptive ring helps accommodate wider focus control systems.
Five rubber O-rings provide weather sealing around key areas, and the aluminum and magnesium alloy housing balances durability with a listed weight of 1.186 kg. Laser-engraved UV-reactive markings remain easier to read in dim production environments. For filmmakers who want a fast 45 mm prime with Micro Four Thirds mounting, feet-based distance markings, and consistent cinema mechanics, this lens combines optical flexibility with practical control.
