The Canon RF 10-20mm F4 L IS STM Lens – a phenomenal ultra-wide-angle marvel that offers impeccably corrected, rectilinear coverage extending down to an astonishing 10mm on full-frame cameras. Whether you're an avid photographer or a video enthusiast, the 10mm ultra-wide-angle effect adds a captivating, dramatic touch to your landscape, architectural, interior, travel, and even photojournalistic shots.
This lens delivers authentic L-Series quality, complete with extensive optical and digital distortion corrections and optical image stabilization (OIS) for exceptional low-light performance, particularly in video shooting. Its autofocus is powered by a tried-and-true STM-type focus motor, ensuring a more compact design without sacrificing rapid AF and seamless focusing during video recording. In addition, this lens provides a remarkable 6.0 stops of image stabilization correction following CIPA standards, thanks to its synchronized IS. The front lens element boasts a Fluorine coating, enhancing durability and making it easy to wipe away oils and fingerprints. Canon's cutting-edge SSC (Super Spectra Coating), advanced ASC (Air Sphere Coating), and SWC (Subwavelength Structure Coating) technologies work in unison to minimize flare, ghosting, and other optical anomalies. The optical excellence of this lens is striking, comprising 16 elements grouped into 12 groups, which includes a super UD element, three UD glass elements, and three aspheric elements. With a minimum focus distance of just under 10 inches at all focal lengths, this lens showcases remarkable versatility.
The lens design prioritizes efficiency, featuring a lightweight build, swift focusing, image stabilization, and a programmable control ring. Additionally, it incorporates a petal-type lens hood seamlessly integrated into the lens barrel, offering added convenience.
Capturing images at 10mm is already extraordinary, but doing so in a lens lighter and smaller than even our own EF11-24mm f/4 L USM is a notable feat. The RF mount design plays a pivotal role in enabling this wider-angle range while contributing to the lens's reduced size and weight. This design innovation also facilitates the incorporation of IS (image stabilization) in a lens that might otherwise not accommodate it.
Excellent Image Quality
Thanks to the Canon RF lens mount, the RF 10-20mm F4 L IS STM lens consistently delivers exceptional optical quality. The optical configuration includes a super UD element, three UD elements, and three aspheric elements, including large-diameter aspheric and UD aspheric elements, along with Subwavelength Structure Coating (SWC) and Air Sphere Coating (ASC) to mitigate ghosting. Moreover, this lens inherits the dust- and water-resistant features characteristic of L-series lenses, with seals protecting the Control ring, focus ring, zoom ring, operation panel, and lens mount.
Make Some Movies
The RF 10-20mm F4 L IS STM lens offers numerous advantages and features for videography. It unlocks the full potential of the 10mm focal length on full-frame cameras, even enabling 4K 60p shooting without a crop mode. APS-C camera users gain access to wider angles than ever before, equivalent to a 16-32mm lens. Another videography benefit is the fixed f/4 aperture, minimizing exposure changes during zooming.
Optical I.S. - Up to 6.0 stops of Shake Correction
For consistently sharp results, the RF10-20mm F4 L IS STM features built-in optical Image Stabilization, delivering up to 5.0 stops of shake correction. Paired with an EOS R-series camera equipped with In-Body Image Stabilization (IBIS), the Coordinated IS extends correction capabilities to an impressive 6.0 stops. This translates to steady hand-held video and exceptionally sharp still images, setting this RF ultra-wide-angle lens apart.
High-speed, Smooth and Quiet Autofocus
Expect swift and precise autofocus with any Canon EOS R-series camera. The STM leadscrew-type focus drive system is especially advantageous for videographers, offering quiet operation and exceptionally smooth focus changes during recording. Additionally, AF during still shooting is both rapid and discreet.
With a minimum focus distance of just under 10 inches, this lens allows for capturing truly incredible ultra-wide-angle close-ups, delivering a visual experience like no other.
