The RF-S10-18mm f/4.5-6.3 IS STM has the shortest focal length of any zoom lens in the RF-S lens lineup. This compact, lightweight lens weighs approximately 150g, and offers an ultra-wide angle of view equivalent to 16-29mm*1 in a 35mm film format. Despite the wide angle of view, it offers an image stabilization effect equivalent to a 4-stop increase in shutter speed*2. This makes it ideal for shooting in tight spaces, where there is no room to step back and capture the entire subject, or when taking selfies where a number of subjects need to be captured in a single frame.
The optical system uses UD and PMo lenses to achieve excellent image rendering performance and compact size, while keeping the number of lens elements to a minimum. The minimum focus distance is 0.14m, and manual focus (MF) mode allows the photographer to get as close as 10cm from the subject. The lens can be attached directly to EOS R series full-frame cameras with no need for a mount adapter.
*1 The 35mm format conversion is equivalent to 1.6x. Focal length in APS-C format is 10-18mm.
*2 When used with EOS R10 camera at a focal length of 45mm. Based on CIPA standards. Effective in the yaw and pitch directions only.
Note: This lens is equipped with a focus/control ring that integrates the focus ring and the control ring.
