Lens Overview — Contax Zeiss 135mm AEJ Cine Modded

The Contax Zeiss 135mm AEJ Cine Modded Lens is a 135mm prime lens built on the Contax/Yashica mount, adapted and modified for modern cinema and video production use. Operating at a maximum aperture of f/2.8, this full-frame lens sits in the telephoto focal length range and is entirely manual focus in operation — a characteristic well-suited to controlled video environments where precision and repeatability matter. The lens has been cine-modded, meaning it has been reworked from its original still-photography configuration to better serve video production workflows.

With a 55mm filter thread, it accepts standard 55mm filters for optical or protective use. Weighing in at 860g, it carries a solid, substantial feel that is consistent with its robust construction and cinema-ready modifications. The Contax/Yashica mount means it will require an appropriate adapter for use on most modern camera systems, but that flexibility makes it compatible with a wide range of cinema and mirrorless bodies via third-party adapters.

For videographers and cinematographers seeking a manual, full-frame telephoto prime with a maximum aperture of f/2.8, this cine-modded lens offers a distinctive shooting experience rooted in classic optical heritage with practical modifications for contemporary production.

The Contax Zeiss 135mm AEJ Cine Modded Lens is a 135mm full-frame prime operating on the Contax/Yashica mount, modified specifically for cinema and video production use. With a maximum aperture of f/2.8, it delivers solid performance in the telephoto focal length range and relies entirely on manual focus — making it a natural fit for video workflows where focus pullers require precise, repeatable control. The lens weighs 860g, giving it a solid and substantial presence on a rig or cinema camera setup.

A 55mm filter thread allows for straightforward integration of standard filters. As a cine-modded lens, it has been reworked from its original still-photography form to better suit the demands of modern video production.
