  • As part of our new RF-S lens line, the RF-S18–45mm F4.5–6.3 IS STM gives you the flexibility you desire without taking up your whole camera bag. This lens was designed with smaller APS-C sensors in mind, and when connected to a full frame EOS R camera, automatically enables the 1.6x crop mode. It offers 100% x 100% Dual Pixel CMOS AF coverage for APS-C sensors, and 80% x 80% Dual Pixel CMOS AF coverage for Full Frame sensors (in crop mode). The small size of the RF-S18–45mm F4.5–6.3 IS STM and clever lens retraction mechanism lets it fit just about anywhere, making it a great lens to bring with you on a walk or wherever the day takes you. The lead screw-type stepping motor (STM) helps ensure smooth autofocus and quiet operation, letting you capture videos with great audio and minimal background noise so you won't distract your subject in a quiet photo environment. Optical Image Stabilization provides up to 4 stops of correction, and up to 6 stops with Coordinated IS. This advanced image stabilization can result in sharper photos with minimal blur, even in low light situations. When you add all of this together, you get a wonderful, lightweight, and versatile lens that is designed to fit into your life.

    Product Highlights:

    Versatile zoom range of 18-45mm

    Excellent image quality with two Aspheric elements and Canon Super Spectra Coating

    Optical image stabilization at up to 4 stops of shake correction

    Product Features:

    Excellent image quality

    Equipped with two Aspheric elements and Canon Super Spectra Coating for beautiful stills. Continuing on a tradition of high-quality lens technology, the two aspheric elements help reduce chromatic aberration throughout the zoom range for excellent image quality with high resolution and contrast, and the Canon Super Spectra Coating helps ensure outstanding color balance while minimizing ghosting and flare.

    Optical image stabilization

    Up to 4 stops of shake correction, and up to 6 stops of shake correction when paired with EOS R series cameras featuring In-Body Image Stabilizer (IBIS). You can capture amazingly clear and steady results while shooting handheld photos or videos, even in low-light situations like indoors or night scenes, without having to significantly increase the ISO or grab a tripod, and when combined with an EOS R Series camera with an In-Body Image Stabilizer, you can experience the additional benefits of Coordinated image stabilization for even more shake correction.

    Quiet stepping motor

    The motor helps provide smooth autofocusing when shooting videos. The RF-S18-45mm F4.5-6.3 IS STM lens uses a gear-type stepping motor to provide smooth and quiet autofocus when shooting both still and video, so focusing appears seamless while following a subject with Servo AF, or Movie Servo AF. Focus racks will have clean transitions when repositioning to another subject, or when focusing from foreground to background.

    Lens-retraction mechanism

    Allows the lens to be retracted by turning the zoom ring for a compact, lightweight and portable design. This updated mechanism (based on EF-M lenses) changes the lock switch to a faster action twist motion that allows the lens to retract into itself for maximum portability.

    Minimum focus distance of 7.9 inches (AF mode)

    This allows shooting at a maximum magnification of 0.16x in AF mode, 0.26x in MF mode (at 45mm). Capture amazing shots wherever you are and whatever your subject, even at a close distance of 7.9 inches at a maximum magnification of 0.26x, making this not just an ideal lens for everyday casual shooting but for more intricate shots like food, flowers and smaller subjects you really want to show off.

    Circular (7 blades) aperture for beautiful, soft backgrounds

    You'll have no problem getting that creative, fun and pleasant out-of-focus background blur we all love with the circular 7-blade aperture, so your subject stands out and the background provides a beautiful backdrop that's visually appealing in itself.
