Lens Overview — Venus Optics 45mm T2 Amber Flare

The Venus Optics Laowa Proteus 45mm T2 is a manual-focus prime anamorphic cinema lens built for the Super 35 format and the Cinema / Video camera system. Mounted in PL, this lens offers a 45mm focal length and a maximum aperture of T2, giving cinematographers solid light-gathering capability alongside the distinct anamorphic look that the format is known for. At 2,600g, this is a substantial optic designed for rigged cinema setups rather than run-and-gun handheld shooting.

The lens is a true prime, meaning the 45mm focal length is fixed, which encourages deliberate compositional choices on set. Focus is entirely manual, which aligns with professional cinema workflows where a dedicated focus puller typically handles critical focus during a take. The filter thread measures 105mm, accommodating large-format matte boxes or screw-in filters suited to a front element of this scale.

There is no image stabilization, which is expected in a cinema lens of this class given that stabilization is typically handled at the rig or gimbal level. The Super 35 lens format means this optic is well-matched to cinema cameras running Super 35 or similar-sized sensors. Overall, the Proteus 45mm T2 is a purposeful, spec-driven anamorphic prime for serious narrative filmmaking.

Description — Venus Optics 45mm T2 Amber Flare

The Venus Optics Laowa Proteus Anamorphic is a 45mm prime lens built for the Super 35 format, offered in a PL Mount for use with professional cinema camera systems. With a maximum aperture of T2, this lens delivers solid light transmission in a fixed focal length form factor — ideal for controlled, narrative cinematography where consistent exposure is a priority. The lens is manual focus only, in keeping with standard cinema production practices where a focus puller manages critical focus using a follow focus system.

Weighing in at 2,600g, the Proteus is a substantial piece of glass that benefits from a proper camera rig and lens support. Its 105mm filter thread is sized for professional-grade matte boxes and large-format filters. The lens type is listed as Anamorphic and is classified as a prime, so there is no zoom capability — the 45mm focal length is fixed.

There is no image stabilization, which is expected for a cinema lens of this class. The Proteus 45mm T2 is a purpose-built cinema optic for filmmakers working with Super 35 cameras on the PL Mount platform.
