Description — Sigma 20mm T1.5 FF
The Sigma Cine 20mm T1.5 FF is a prime wide-angle lens built for cinema and video production on full-frame camera systems. Its T1.5 maximum aperture delivers fast, precisely measured light transmission — a critical feature when matching exposure across a set of cinema primes on a professional production. The 20mm focal length falls in wide-angle territory, offering a broad field of view suited to interiors, environmental storytelling, and dynamic establishing shots.
As a manual focus lens, it integrates seamlessly into standard cinema rigging setups with follow focus systems and lens control motors. Mount compatibility spans PL Mount, Canon EF, Sony E, and L-Mount, allowing this single lens to serve across a diverse range of professional and hybrid cinema cameras. The full-frame image circle ensures edge-to-edge coverage on the largest sensor formats in current use, with no image circle limitations to worry about on full-frame platforms.
