The Canon RF 15-35mm f/2.8L IS is part of Canon's EOS R system. To support the optical technologies of this new system, a new mount type RF has been introduced. RF lenses take full advantage of the benefits of a mirrorless design. Here are some of the top features of this system and this lens:

• Shorter distances between RF lenses and EOS R system cameras reduced from 44mm in the EF/EF-S system to a mere 20mm. Having larger optical elements very close to the sensor means fewer aberrations, greater brightness, and better image performance overall.
  
• Unique ability to assign custom shooting functions directly on the lens, like aperture value, shutter speed, ISO adjustment, and exposure compensation. Rotation clicks give you the sensory cue needed to make these settings changes while composing your shot.
  
• Up to 7 stops of correction thanks to Optical Image Stabilization which works in tandem with the EOS R system's In-Body Image Stabilization systems.
  
• Good for use in inclement weather thanks to protective coatings.
  

  
  The wide 15-35mm length is the perfect range for landscapes, cityscapes, and events. The bright f/2.8 maximum aperture is maintained throughout the entire zoom range. Go from shooting landscapes to group portraits in a lens that is well-balanced and able to perform in very low light environments.
