OVERVIEW  
The RF-S10-18mm F4.5-6.3 IS STM lens combines excellent optics and high performance, providing an ultra-wide angle of view in a compact, portable package, perfect for EOS R cameras with an APS-C sensor. The optical performance is a direct result of a totally new lens design, highlighted by two Ultra-low Dispersion glass elements and an Aspheric element. The RF-S10-18mm F4.5-6.3 IS STM delivers reliable, speedy and quiet wide-angle performance, making it an ideal lens for vlogging, video, travel, landscapes, interiors, or simply for creative imagery. 
 
FEATURES 
 
Ultra-wide-angle Lens 
The RF-S10-18mm F4.5-6.3 IS STM lens’ wide coverage picks up right where the RF-S standard zooms leave off, at 18mm, and from there it widens to true ultra-wide coverage at its 10mm focal length. This ultra-wide-angle 10-18mm (16-29mm equivalent) is great for shooting in tight spaces where stepping back is difficult such as vehicles and small rooms, or for landscape, travel, and more.  
 
Outstanding Image Quality 
The RF-S10-18mm F4.5-6.3 IS STM features a new lens design optimized for short back focus with two Ultra-Low Dispersion glass elements and an Aspheric element which achieves high image quality throughout the image from center to the edges while maintaining compactness. Even at its widest zoom setting, both optical and digital corrections combine to minimize any risk of darkening at the edges or bending of straight lines in a scene. 
 
Get Up Close 
Capture subjects in large detail with a maximum magnification of 0.23x in AF mode (focusing down to 5.5 inches), and 0.5x in MF mode. This enables richly expressive close-up shots using the wide angle of view and bokeh an ultra-wide-angle lens can provide. 
 
 
Optical Image Stabilization — Up to 4.0 stops1 of Shake Correction   
 
To shoot with less blur even without a tripod handy, the RF-S10-18mm F4.5-6.3 IS STM features built-in Optical Image Stabilization, providing up to 4.0 stops1 of shake reduction even for night shots. When paired with an EOS R-series camera that has In-Body Image Stabilization (IBIS), the Coordinated IS allows for up to 6.0 stops2 of correction. This makes hand-held video, travel photography, or even taking everyday shots convenient with less equipment to carry.

2 At focal length of 18mm with EOS R7. Yaw/Pitch directions only. 
 
High-speed, Smooth and Quiet Autofocus 
 
The lens features a leadscrew-type STM focus drive system which provides smoother and more natural movie AF. This is especially beneficial to video users because of its combination of quiet operation and outstanding smoothness of focus changes during actual recording. Plus, it supports focus breathing correction1, in which the camera digitally corrects for changes in angle of view caused by focus movement during video recording.

Compact and Lightweight 
 
At approximately 5.3 ounces (150g), the RF-S10-18mm F4.5-6.3 IS STM is extremely lightweight and compact. The lens also features a lens-retraction mechanism that works without a switch, allowing it to be stored compactly simply by turning the zoom ring for outstanding portability.
