Description — Leitz 21mm T2.1
The Leitz ELSIE 21mm T2.1 is a prime cinema lens with a 21mm focal length and a maximum aperture of T2.1, designed for professional film and video production. It uses the L-Mount lens mount and is built to cover a full-frame image format, making it a strong fit for full-frame cinema and mirrorless cameras in the L-Mount ecosystem. Focus is fully manual, which suits the demanding, controlled environments of professional cinematography where focus pullers rely on precise, repeatable movements.
The lens sits in the wide-angle focal length range, making it well suited to environmental shots, tight interior spaces, and expansive scene-setting frames. Weighing in at 2.4041 kg, this is a substantial lens that demands proper rig support. Image stabilization is not present, consistent with professional cinema use where stabilization is managed at the rig or camera level. No filter thread is specified, so matte box or clip-on filter solutions should be factored into any kit build around this lens.
