Obiettivo Irix Cine 45mm T1.5 Micro Four Thirds metrico

When shooting narrative film or commercial work, achieving a cinematic look with precise focus control and consistent exposure is critical. The Irix Cine Lens 45mm T1.5 for Micro Four Thirds mount delivers exactly that—a fast, manual-focus prime lens built for professional video production. With a bright T1.5 aperture, it excels in low light and provides beautiful shallow depth of field, while the metric focus scale and 180° focus rotation allow for smooth, repeatable focus pulls. Its full-frame image circle ensures edge-to-edge sharpness even on MFT sensors, and the robust weather-sealed construction means you can rely on it in challenging environments.

Who is it for

This lens is ideal for cinematographers, videographers, and independent filmmakers using Micro Four Thirds cameras who demand high optical quality and precise manual control.
