Canon RF 50mm f/1.8 STM
Canon RF 50mm f/1.8 STM


The Canon RF 50mm f/1.8 STM is part of Canon's EOS R system, one of Canon's most important releases since the EOS system began about 30 years ago. Learn more about the EOS R system and the standout features of this lens:

  • • The distance between the RF lens' mount and the surface of the EOS R sensor has been 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.
  • • The number of contact pins has been increased, elevating the speed and volume of communication between the lens and camera. This is supported by a new microprocessor within the lens that increases communication without significantly increasing power consumption.
  • • Taking advantage of the communication features listed above, RF lenses provide the unique ability to assign custom shooting functions directly to the lens. A special tactile control ring on the barrel of this lens can be assigned to functions like aperture value, shutter speed, ISO adjustment, and exposure compensation.
  • • Incorporating a stepping motor (STM) focus drive system, this lens exhibits smooth, silent, and ultra-quick AF performance to meet the demands of video shooting.
  • • This lens offers a large maximum aperture with a close focusing distance (under a foot from your subject), and extreme portability (this lens is under 2" long and less than a pound).
  • • Super Spectra coatings control flare and ghosting while special aspheric lens elements maintain subject sharpness and reduce distortion even at the widest apertures.

    The Canon RF 50mm f/1.8 STM is a sharp prime lens that's an ideal choice for street and lifestyle photography as well as for portraiture. Its smooth AF performance makes it perfect for shooting video and would be a great photo/video hybrid lens for weddings and other major events.
