Lens Overview — DZOFilm 40mm T2.1

The DZOFilm VESPID 40mm T2.1 is a prime cinema lens built for full-frame camera systems, covering the standard focal length range at a fast T2.1 maximum aperture. Designed for the Cinema/Video camera system, this lens is available in both PL Mount and Canon EF mount configurations, making it a flexible option for cinematographers working across different camera platforms. As a manual focus lens with no autofocus capability, it is purpose-built for controlled cinematic shooting where precise, repeatable focus pulls are a priority.

Weighing in at 800g, the VESPID 40mm sits in a practical weight class for a full-frame cinema prime, balancing portability with the build quality expected from a dedicated cine lens. The T2.1 aperture rating — measured as a true T-stop rather than an f-stop — reflects actual light transmission, which is critical for consistent exposure matching across a set of cinema lenses. At 40mm on a full-frame format, this focal length sits in versatile standard territory, well-suited to a wide range of narrative and documentary applications.

Image stabilization is not present in this lens, which is standard for a cinema prime intended for use on stabilized rigs or gimbals.

The DZOFilm VESPID 40mm T2.1 is a prime cinema lens designed for full-frame format camera systems operating in Cinema/Video applications.

The lens is offered in PL Mount and Canon EF mount variants, giving cinematographers flexibility across different camera bodies.

With a manual focus design and no autofocus, the VESPID 40mm is built for deliberate, controlled shooting environments typical of narrative film and high-end video production.

What camera mounts is the DZOFilm VESPID 40mm T2.1 compatible with?+
The lens is available in PL Mount and Canon EF mount configurations. These are the two mount options listed in the specifications, so buyers should confirm which mount version they are purchasing to ensure compatibility with their camera system.
Does this lens support autofocus?+
No. The DZOFilm VESPID 40mm T2.1 is a manual focus lens only, with no autofocus capability. This is a deliberate design choice suited to cinema workflows where focus pullers operate the lens manually.
What sensor size does this lens cover?+
The VESPID 40mm T2.1 is designed for full-frame format sensors, which is the largest common sensor format. This makes it compatible with full-frame cinema and hybrid camera systems.
What is the difference between a T-stop and an f-stop rating?+
A T-stop, like the T2.1 on this lens, measures actual light transmission through the lens, whereas an f-stop is a geometric calculation. T-stops are preferred in cinema because they allow consistent exposure matching across different lenses in a set.
How heavy is the DZOFilm VESPID 40mm T2.1?+
The lens weighs 800g according to the specifications. This is a moderate weight for a full-frame cinema prime and should be accounted for when planning rig and support system configurations.
