Features

Overview: The Canon RF-S 10-18mm f/4.5-6.3 IS STM is a compact ultra-wide angle zoom lens with an ideal zoom range for selfies, vlogging, interior, architecture, and landscape photography. It fits R-series mirrorless cameras, and was designed for cameras with the smaller APS-C images sensors. The lens offers 100% x 100% Dual Pixel CMOS AF coverage for APS-C sensors, found on the Canon EOS R7 and R10 cameras. On cameras with Full Frame sensors (EOS-R5, EOS-R3), the lens provides 80% x 80% Dual Pixel CMOS AF coverage in 1.6x crop mode. Its unique lens retraction mechanism keeps the lens short, making it ideal to carry with you wherever you go. Its Optical Image Stabilization provides up to 4 stops of correction on most cameras, and up to 6 stops with EOS-R cameras with In-Body Image Stabilization (IBIS), such as the EOS R5.

Lens Construction: The lens is constructed of 12 lens elements in 10 groups, including 1 aspherical lens element for superb image clarity from the center to the edges of the frame, and 2 Ultra-low Dispersion (UD) lens elements to reduce aberrations and distortion. The lens has Canon's Super Spectra Coating (SSC) minimizes ghosting and flare, and ensures a consistent color balance across all lens elements.

12-pin Communication: The Canon RF-series lenses feature a 12-pin communication system between the camera and the lens (compared to 8 pins for the EF-series). This 12-pin system is the fastest available for a Canon lens and camera combination, and provides faster AF, Image Stabilization, Digital Lens Optimizer, and more. In addition, the EOS R camera can display lens information directly to the viewfinder, making it easy to confirm the lens' focal length without looking away from your subject.

Dual Function Manual Focus/Control Ring: The RF-S 10-18mm lens features a dual-function manual focus ring/control ring. The electronic ring can be used for full-time manual focus, and has no physical limit to its rotation. You can switch the function of the ring to serve as a Control Ring in the menu of the camera. There is no physical switch on the lens. The control ring function lets you make a variety of adjustments, such as aperture, shutter speed, ISO speed, or exposure compensation.

Stepping Motor: The lens is equipped with a Lead Screw-type stepping motor (STM) that provides smooth and quiet auto focusing. When you press the shutter button halfway, the stepping motor rotates the lead screw which moves the focus lens in and out. Because it operates in near silence, no focusing noise is picked up by the microphone when shooting video.

Image Stabilizer (IS): The RF-S 10-18mm lens features Optical Image Stabilization (IS) when mounted to a Canon EOS R series camera. The camera and the lens share data to dramatically reduce blur caused by camera shake while shooting still images and videos. Image Stabilization can be turned on or off with the switch on the lens barrel. When paired with the Canon R5 or R6 cameras, which have In-Body Image Stabilization, the effect of Coordinated IS is equivalent to 6 stops. On other EOS R and RP cameras, the optical image stabilization effect is equivalent to 4 stops.

Optional Accessories: Canon offers two accessories for the RF-S 10-18mm lens:

• Lens Hood: The optional petal-shaped EW-53B bayonet-type lens hood (sold separately) cuts out unwanted light and protects the front of the lens from rain, snow, and dust. When attached to the lens, the hood adds approximately 1" to the overall length of the lens. When not in use, you can reverse-mount the lens hood for storage.
• Lens Case: The RF-S 10-18mm lens can be protected with the optional soft Lens Case LP814 (sold separately).

Optional Filters: The RF-S 10-18mm lens has a 49mm mounting thread on the front of the lens for attaching screw-on type filters.
