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. They’re 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 subrental at Cine Visuals.

Image Performance

Handling & Adaptability

The inclusion of a single aspheric optical element makes it visually compatible with both the multi-aspheric Leica Summilux-C and the spherical Leica Summicron-C primes. With nine lenses in six groups and apochromatic correction, outstanding resolution and contrast can be achieved all the way to the edge of the frame.
