IRIX Cine Lens 21mm T1.5 for MFT Metric

Professional cinema prime lens with a 21mm focal length and ultra-fast T1.5 aperture, delivering a 90° field of view on full-frame sensors and exceptional low-light performance. Its 11-blade rounded aperture creates smooth, cinematic bokeh, while the stepless de-clicked iris allows silent exposure adjustments during shooting. Built for Micro Four Thirds mounts but covering full-frame image circle, this lens is ideal for narrative film, documentary, and commercial production. The metric focus scale and 180° focus rotation enable precise manual focusing, and the rugged aluminum-magnesium alloy body with weather sealing ensures reliability in challenging environments.

Advantages

The T1.5 maximum aperture excels in low light and provides shallow depth of field for subject isolation. The 11-blade rounded aperture produces organic, pleasing out-of-focus highlights. The stepless de-clicked iris is essential for smooth aperture pulls without clicks or jumps. The 0.8 MOD gear rings on focus and iris are compatible with standard follow focus systems, allowing repeatable and accurate lens control. The internal focusing design prevents lens length change, making it ideal for use with matte boxes and stabilizers. Weather sealing with three rubber seals protects against dust and moisture, extending usability in adverse conditions. The aluminum-magnesium alloy construction offers a lightweight yet durable build, suitable for rigorous professional use.
