The native RF mount offers high speed communication between the lens and camera body, with the enhanced design allowing for a more stable and comfortable experience when operating.

The lenses are compatible with the EOS C70 (released in November 2020) and EOS R5 C3 (released in March 2022) RF Cinema cameras. Fully compatible with the transmission protocol of the RF mount, and as with EF mount Prime series lenses, operators can control magnification, chromatic aberration correction, peripheral light correction, and a dual pixel focus guide via camera body operations. In addition to these functions, the new lenses feature distortion aberration correction4. These features support efficient video production not only during on-location recording but also post-shoot editing.

The new lenses achieve exceptional optical performance, excellent colour reproduction and are suitable for use with 4K and 8K cameras – optimally positioning large-diameter aspherical lens elements and lens elements with anomalous dispersion glass. Their compatibility with the full-frame large-format sensor, bright T-stop values5, and the use of 11 aperture blades allow for a shallow depth of field for subjects, natural round blurring, and soft image expressions. In addition, since the colour balance is unified throughout the series, adjusting colour tones when changing lenses while shooting the same scene can be done with ease.

With precise adjusting of the operation ring, the new lenses allow smooth and accurate adjustments that are required for cinema shooting. In addition, due to the unified design across the series, including the gear position of the operation ring, the diameter of the lens and the rotation angle (operation angle), the lens can be exchanged smoothly without the need to adjust the mounting position of the matte box or external follow focus accessories for each model6. A new knurled surface near the mount provides a comfortable fit in the user’s hand, allowing the lens to be held securely without gripping the operation ring when attaching and detaching different lenses.
