Description — Sigma 50mm T2.5
The Sigma 50mm T2.5 Cine Lens is a dedicated prime cinema lens built for professional filmmaking. With a 50mm focal length and full-frame coverage, it addresses the needs of cinematographers working on large-sensor cinema cameras. The lens mounts via PL Mount, integrating cleanly into professional cinema production setups.
A maximum aperture of T2.5 provides reliable light transmission, while the fully manual focus design supports traditional cinema focus-pulling techniques using follow focus systems. The 95mm front filter thread is a consistent diameter that simplifies the use of shared matte boxes and filter accessories across a lens set. At 970g, the lens carries the weight expected of a professional cine prime, built for durability in production environments.
With no image stabilization and no autofocus, this lens is purpose-built for controlled cinema production workflows where manual operation is the standard. Its classification as a standard focal length prime in the Cinema/Video camera system makes it a straightforward, reliable choice for cinematographers building out a professional prime lens set.
