Description — Cooke 100mm T2.4
The Cooke SP3 100mm T2.4 is a prime cine lens built for Sony E mount mirrorless cameras, purpose-built for filmmakers working in Super 35 format. With a fixed 100mm focal length and a maximum aperture of T2.4, it delivers a consistent, measured exposure across a matched set of SP3 primes — a critical requirement on professional sets where intercutting between lenses demands exposure continuity. The lens is manual focus only, putting full control in the hands of a dedicated focus puller or operator.
At 690g, it is light enough to mount on gimbals and stabilizer rigs without excessive payload concerns. The 77mm filter thread integrates smoothly with standard matte box systems and screw-in filter accessories common on professional sets. There is no image stabilization built in, so stable footage depends on rig design or in-camera stabilization.
The telephoto focal length classification makes this lens well suited to medium close-ups, portraits, and compressed-perspective shots in narrative and documentary production.

Frequently Asked Questions — Cooke 100mm T2.4
Does the Cooke SP3 100mm support autofocus on Sony E mount cameras?+
No. The SP3 100mm is a fully manual focus lens with no autofocus capability. It is designed for cine production workflows where manual focus pulls are standard practice.
What sensor size does this lens cover?+
The SP3 100mm is designed for a Super 35 image circle. It is mounted on Sony E mount mirrorless cameras but is optimized for Super 35 format sensors rather than full-frame.
What does the T2.4 aperture rating mean on this lens?+
T2.4 is a T-stop rating, which measures actual light transmission through the lens rather than the theoretical f-stop value. T-stops are standard in cinema lenses because they allow consistent exposure matching across a set of primes.
How heavy is the Cooke SP3 100mm and is it suitable for gimbal use?+
The lens weighs 690g, which is relatively manageable for a cine prime. Its weight and compact form factor make it a reasonable candidate for gimbal and stabilizer rigs used in film production.
What filter size does the SP3 100mm use?+
The lens has a 77mm filter thread, a widely used size that is compatible with many standard matte boxes, filter holders, and screw-in filter systems.
Does this lens have image stabilization?+
No, the SP3 100mm has no built-in image stabilization. Shooters should rely on in-body stabilization if available on their Sony E mount body, or use an external stabilized rig.
