Laowa Proteus 45 mm T2 2× Anamorphic S35 (Blue, PL + EF) unlocks a panoramic 2.66 : 1 frame on a 4 : 3 sensor with a constant 2× squeeze and covers a 25.9 mm image-circle – enough for Super 35+ cameras such as ALEXA 35 and RED V-RAPTOR. The 45 mm focal length supplies a natural field of view (horizontal 59.9°, vertical 27°) while preserving the perspective compression prized for medium shots.
The fast T2 – T22 aperture teams with a 10-blade iris and a 17-element / 14-group optical formula to deliver crisp centre-to-edge resolution at wide-open stops, elongated oval bokeh and a vivid blue anamorphic flare signature. A floating focusing cell maintains flat-field sharpness from the minimum 0.55 m to infinity, and the squeeze ratio never drifts, eliminating “mumps”. Focus breathing stays beneath the perceptible threshold, ensuring undisturbed framing during pulls.
Professional mechanics match the optical performance. The 300° focus throw with 0.8 MOD cine gears and a unified 114 mm front diameter keep the lens compatible with industry follow-focus units and matte boxes, while a 60° iris ring enables precise exposure trims. The robust housing weighs 2.4 kg and measures 182 mm, so handheld, Steadicam or drone rigs remain balanced. A 105 mm front thread accepts diopters or NDs, and a rear shim stack plus accessible back-focus collar allows on-set collimation.
Ships in ARRI PL configuration with an included Canon EF bayonet, and electrical-contact-free construction for maximum reliability. Add Laowa’s optional 1.4× expander to illuminate full-frame sensors at 2.8× squeeze. Constant squeeze, minimal distortion and neutral colour render make this lens a precise tool for feature production, live broadcast drama, studio commercials or virtual-production volumes seeking authentic widescreen character without unwanted artefacts.
