L Series Optics
Featuring an optical design based on past EF and RF super-telephoto lenses, this lens features top-range optics designed for the most demanding shooting applications.
Two fluorite, one Super Ultra Low-Dispersion (UD), and one UD element virtually eliminate chromatic aberrations for outstanding clarity and color accuracy, void of chromatic aberrations or fringing.
Advanced optical design also contributes to the sleeker, more portable form factor of this RF-mount, mirrorless lens.
Both Air Sphere and Super Spectra Coatings improve image quality by maintaining high contrast and color accuracy while reducing lens flare and ghosting when working in strong lighting conditions.

Two focus presets can be stored for immediate recall to a specified focus distance.
Focus range limiter improves responsiveness by constraining the usable focusing range.
Benefitting handheld and monopod-based shooting, Optical Image Stabilization compensates for 4.5 stops of camera shake for sharper imagery. Due to the long focal length, in-body image stabilization, or Coordinated IS, from EOS R-series bodies is not supported with with this lens.
