DESCRIPTION
Canon RF 800mm f/5.6L IS USM Overview
Powerful Reach, Unprecedented Portability
Relatively sleek despite its super-telephoto reach, the Canon RF 800mm f/5.6 L IS USM is an impressive prime meshing top-of-the-line performance with an updated compact and lightweight design. Ideal for sports, wildlife, and journalism applications, this long lens offers a distinctly tight field of view for isolating distant subjects, along with responsive AF and image stabilization, reliable weather-sealing, and intuitive handling for dependable use in fast-paced situations.
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 8.5' minimum focusing distance, and a maximum magnification of 0.34x, 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 4.5 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.
Intuitive Handling and Professional Reliability
- Relatively lightweight and compact, this 800mm f/5.6 lens weighs 6.9 lb and measures 17"-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 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.
- Compatible with optional Extender RF 1.4x and 2x teleconverters for further extending the effective reach of this lens.
