MasterBuilt Classic Primes
Prime - Spherical - Full Frame
product details
MasterBuilt Classic Primes are a modern lens set inspired by the aesthetics of vintage cinema glass. These full frame spherical primes are prized by filmmakers for creating a timeless cinematic mood. Theyโre often chosen for period dramas, music videos, and commercials where a nostalgic, filmic character is more important than technical perfection. Their rendering is lower in contrast, with smooth highlight roll-off and pleasing softness that evokes mid-20th-century glass. Available focal lengths: 18mm, 25mm, 35mm, 40mm, 50mm, 65mm, 85mm, 105mm and 135mm, with T1.4 apertures across the set. Available for rental or sub-rental at Cine Visuals.

MasterBuilt Classic Primes
Image Fidelity & Focus
Classic Primes are designed with character in mind. They deliver moderate sharpness with flattering skin-tone reproduction, subtle edge softness and organic micro-contrast for an organic feel. Contrast is slightly lower than in clinically modern lenses, giving images a filmic quality. Focus falloff is smooth. Chromatic aberrations are present but intentional, reinforcing the vintage-inspired rendering.
Handling & Adaptability
The Classic Primes feature robust, modern cine housings with consistent mechanics, and are highly adaptable for digital cinema. Their weight is moderate, suitable for both studio and handheld work.
Flare & Bokeh
Flare is expressive but cinematic, producing veiling and rainbow streaks when pushed. Bokeh is soft and creamy, with occasional swirls that add atmosphere and enhance subject isolation.
Image Circle
MasterBuilt Classic Primes cover Full Frame sensors.
Cinematic Heritage
MasterBuilt, known for boutique design, created the Classic Primes to respond to the demand for modern glass with vintage character. Unlike rehoused lenses, they are original designs built to evoke the warmth and imperfection of earlier optics.
