Description — Kern 75mm f/1.9
The Kern 75mm f/1.9 Switar is a prime lens built around a C-Mount / 2/3-inch format specification, designed for cinema and video camera systems. With a fixed focal length of 75mm placing it in the telephoto range, this lens delivers a consistent, deliberate angle of view with no zoom adjustment required. The maximum aperture of f/1.9 provides meaningful light-gathering ability, supporting work in a variety of lighting conditions.
Featuring manual focus only — with no autofocus and no image stabilization — the Switar is built for operators who want direct control over every aspect of the image. The C-Mount interface makes it compatible with a wide array of cinema, video, and adaptable mirrorless camera bodies. No filter thread size is listed in the specifications, so shooters should verify filtration options before committing to a filter system.
The prime construction and C-Mount heritage make this lens a focused, single-purpose tool for video and cinema use.
