Description — Canon 14-35mm T1.7 S35
The Canon CN-E Flex Zoom 14-35mm T1.7 is a professional cinema zoom lens mounted in the Canon EF configuration, designed for Super 35 format cinema and video production. It delivers a wide-angle focal length range from 14mm to 35mm with a constant maximum aperture of T1.7, allowing cinematographers to maintain consistent exposure and depth-of-field rendering throughout the zoom range without compensating for aperture shift. The lens operates in manual focus only, which suits professional cinema sets where dedicated focus pullers and follow-focus systems are the standard.
With a weight of 3.3 kg, this is a solidly built professional optic that demands appropriate lens support and rigging. The Super 35 format coverage makes it a natural fit for a broad range of professional cinema camera platforms. The wide-angle focal range makes it well suited for establishing shots, interiors, and environmental storytelling.
The absence of image stabilization means external stabilization solutions should be planned for handheld or moving camera applications. The Canon EF mount ensures compatibility across a range of Canon Cinema EOS and EF-compatible bodies.
