Irix Cine 45mm T1.5 attacco PL obiettivo imperiale

Cinematographers often struggle to find a lens that balances fast aperture, robust build, and precise manual control without breaking the bank. The Irix Cine 45mm T1.5 PL-mount Imperial lens solves this by delivering a true cine-style design with a bright T1.5 aperture, full-frame coverage, and a durable, weather-sealed construction—all in a compact, affordable package.

Who is it for

This lens is built for professional filmmakers, videographers, and rental houses who demand consistent optical performance and reliable mechanics. It suits narrative productions, documentaries, music videos, and commercial work where a 45mm focal length offers a natural perspective with minimal distortion. The Imperial focus scale (feet/inches) is ideal for crews working in regions that use imperial measurements.
