Lens Overview — Leica 50mm T1.4

The Leitz Cine 50mm T1.4 Summilux-C is a professional cinema prime lens built for demanding production environments. Carrying the storied Summilux-C designation, it represents a serious tool for cinematographers who prioritize optical consistency and mechanical precision. At 50mm, it falls squarely in the standard focal length range, making it a versatile choice for a wide variety of shots — from interviews to dramatic close-ups and general coverage work.

The lens is designed around a Super 35 image format, aligning it with the most widely used sensor size in professional digital cinema cameras. It mounts via the industry-standard PL Mount, ensuring compatibility with the broadest range of professional cinema camera bodies. The maximum aperture of T1.4 — a true transmission rating rather than a geometric f-stop — means what you see on the spec sheet is what you get in terms of light delivery, a critical factor when matching exposures across a lens set.

Focus is entirely manual, as expected of a dedicated cinema lens, allowing focus pullers to work with precision and repeatability. The 95mm filter thread accommodates large-format filtration needs. Weighing 1.8kg, it is a substantial lens that reflects its professional-grade construction.

Description — Leica 50mm T1.4

The Leitz Cine 50mm T1.4 Summilux-C is a dedicated cinema prime lens built for professional film and television production. It features a maximum aperture of T1.4, a true transmission-rated T-stop that ensures accurate and consistent light delivery — critical when working across a matched lens set. The lens is designed for the Super 35 image format, covering the sensor size that underpins the majority of professional digital cinema cameras in use today.

Mounted via the PL Mount, it integrates directly with the professional cinema camera ecosystem without compromise. At 50mm, it sits in the standard focal length range, offering a natural perspective that suits a broad range of shooting scenarios. Focus is manual only, in keeping with professional cinema production practices where a dedicated focus puller demands full mechanical control.

The 95mm filter thread supports large professional filtration. At 1.8kg, the Summilux-C is a precision instrument that rewards a properly configured rig and an experienced crew.

Frequently Asked Questions — Leica 50mm T1.4

What camera mount does the Leitz Cine 50mm T1.4 Summilux-C use?+
The lens uses a PL Mount, which is the industry-standard mount for professional cinema cameras. This makes it compatible with a wide range of cinema camera bodies that accept PL Mount lenses.
What sensor size does this lens cover?+
The Summilux-C 50mm T1.4 is designed to cover a Super 35 image format. It is optimized for cinema cameras using this sensor size, which is the most prevalent format in professional digital filmmaking.
Is the T1.4 aperture the same as f/1.4?+
Not exactly. T1.4 is a T-stop rating, which measures actual light transmission through the lens rather than the geometric aperture. This makes T-stop ratings more reliable for matching exposure across multiple lenses on a production, which is why cinema lenses use T-stops rather than f-stops.
Does this lens have autofocus or image stabilization?+
No. The Leitz Cine 50mm T1.4 Summilux-C is a manual focus lens with no autofocus or image stabilization. This is standard for dedicated cinema lenses, where manual focus control by a dedicated focus puller is the norm on professional sets.
What filter thread size does this lens use?+
The lens has a 95mm filter thread. This large diameter is typical of high-speed cinema prime lenses and accommodates professional matte boxes and large-format filter systems.
How heavy is the Leitz Cine 50mm T1.4 Summilux-C?+
The lens weighs 1.8kg. This is a substantial weight that reflects its professional cinema construction, and it should be factored into rig balancing and support system planning.
