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.
Rounded nine-blade diaphragm contributes to a smooth bokeh quality.
USM Autofocus and Image Stabilization
Ultrasonic Motor delivers fast, accurate, and near silent autofocus performance to benefit both photo and video applications.
Impressively close 14.1' minimum focusing distance, and a maximum magnification of 0.29x, suit working with nearby subjects, such as close-range wildlife, birds, and athletes.
Variable speed manual focusing offers three options for greater focusing control and full-time manual focus support permits making focus adjustments without switching modes.
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 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.
Intuitive Handling and Professional Reliability
Relatively lightweight and compact, this 1200mm f/8 lens weighs 7.4 lb and measures 21.1"-long, making it realistic to use atop a monopod or even handheld for short periods of time.
Built-in rotating tripod mount suits working with the lens atop a monopod or tripod and enables quick switching between vertical and horizontal shooting orientations.
Weather-sealed design for reliable use in inclement conditions.
Fluorine coating on the front element helps repel moisture, dust, and fingerprints and is also easier to clean.
Distinctive heat-resistant white paint finish.
Accepts drop-in style 52mm filters toward the rear of the lens.
