WIDER FIELD OF VIEW
The 0.71× focal reducer expands the Alexa’s effective field of view, giving full-frame lenses a much wider perspective on the Super 35 sensor, while keeping the character of the glass intact.

+1 STOP OF LIGHT
By concentrating the lens’s image circle onto the Super 35 sensor, REDUXA A1 delivers roughly one additional stop of light, giving you more exposure without changing lenses or lighting.

ELECTRONIC EF CONTROL
Compatible EF lenses retain electronic communication through REDUXA A1, allowing aperture to be controlled directly from the camera for a cleaner, more integrated shooting setup.

EF & PL
REDUXA A1 comes with positive-lock EF as standard, with a PL mount designed to fit directly over it. Both options provide a secure, rock-solid connection for professional lens setups.
