Constant T2.4 Throughout Range
A constant T2.4 maximum aperture enables low-light capture throughout both the 20-50mm and the 45-135mm zooms' entire focal length range.
8K Optical Performance
These zoom lenses produce the warm color balance and beautiful skin tones that are consistent across the Canon cinema line. Each lens is ideal for 4K-8K HDR capture with a tonal range that reproduces natural-looking images with reduced chromatic aberration and minimal flaring and ghosting.
The interchangeable-mount Flex zooms offer both Canon EF and ARRI PL mount options, enabling you to use them with a wide array of cine-style cameras.
Full-Frame Sensor Coverage
The Flex Zooms cover full-frame cinema camera sensors and are ideal for creating nuanced images with bokeh and shallow depth-of-field looks.
An 11-blade aperture creates natural-looking bokeh across the minimum to maximum aperture range and a gently diffused look when capturing subjects with a bright glow.
Consistent gear placement, front-diameter size, and gear rotation ranges make it easy to switch between the 20-50 and 45-135mm Flex Zooms. Industry-standard 0.8 MOD gear rings, luminous focus marks, and a durable build make these compact zooms easy with which to work.
