RED PRO PRIME 300mm

RED Pro Prime 300mm T2.9 is a high-performance telephoto cinema lens that occupies a unique spot in the RED Pro Prime lineup. Often compared to the Arri/Zeiss Ultra Primes in terms of clinical sharpness and color rendering, this lens was designed to provide a “future-proof” solution for high-resolution digital sensors.

Despite its heavy build (approx. 5.7 lbs / 2.6 kg), it is highly regarded for its minimal “breathing” during focus pulls and its ability to maintain edge-to-edge brightness. It covers Super 35 formats natively and can cover many Full Frame/Large Format sensors with minimal vignetting, making it a versatile long-reach tool for sports, wildlife, and compressed cinematic portraiture.

Key Features and Benefits

High-Resolution Optimization: Specifically engineered to complement 4K, 5K, and 6K sensors, delivering exceptional sharpness and contrast for digital cinema.

Fast Telephoto Speed: Features a bright T2.9 maximum aperture, allowing for shallow depth of field and superior performance in lower light conditions compared to standard telephoto zooms.

Exceptional Optical Design: Utilizes Extra-low Dispersion (ELD) and anomalous dispersion glass to virtually eliminate chromatic aberration and fringing.

Cinema-Grade Mechanics: Built with “tank-like” robust housing, featuring a 270° focus rotation and standardized 0.8 pitch gearing for precise follow-focus control.

Beautiful Bokeh: Optimized iris design produces smooth, circular out-of-focus highlights and excellent subject separation.

Internal Focusing: The lens length remains constant during focus pulls, preventing balance shifts on gimbals or specialized rigs.

Broad Compatibility: While optimized for RED sensors, the native PL Mount ensures it works seamlessly with ARRI, Sony Venice, and other professional cinema systems.
