Press release:

Going Wide: Canon introduces the RF 10-20mm F4 L IS STM to its lens lineup
MELVILLE, NY, October 11, 2023 -
Today, Canon U.S.A., Inc., a leader in digital imaging solutions, announced the launch of the RF10-20MM F4 L IS STM lens, a full-frame ultra wide- angle lens that can help the work of a professional photographer or serious enthusiast stand out from the crowd.

Opening the door to supreme full-frame visual possibilities, the RF10-20MM F4 L IS STM lens continues Canon's respected reputation for optical excellence associated with L-series lenses. This new addition enhances optical performance with a modern mirrorless lens design that is fully equipped with key features, including:

  • New Image Stabilization (IS) technology, to help minimize wide-angle "fluttering" at outer areas of frame
  • Impressively compact size and light weight (1.25lbs/570g) at half the weight of EF series 11-24mm f/4 L lens
  • Super quiet Canon STM focus drive motor, which is ideal for video and marking the first time this technology appears in a Canon L-series lens

Speaking directly to the professional video and stills visual storyteller, the RF10-20MM F4 L IS STM features a built-in lens hood and lens function button on the barrel for customizing functions such as AF settings, Pre-Recording, Zebras and more. For landscapes, cityscapes, architectural, real estate and weddings, the RF10-20MM F4 L IS STM lens is a widely important lens for any professional to have at the ready.

Canon's latest RF mount wide angle, the 10-20mm f/4 L IS USM is a doozy. Nearly half the size and substantially less expensive than the EF version, it also goes even wider! Find out how this little marvel performs on the streets of Calgary in this week's episode.
