The new RF-S series of lenses is designed for use with RF mount cameras with APS-C size CMOS sensors. This lens realizes compact and lightweight designs and provide the same high image quality and high performance of the EOS R system. RF-S lenses can even be used on full-frame EOS R cameras¹, thus expanding the range of lenses for users to choose from.

The RF-S18-150mm F3.5-6.3 IS STM features a 35 mm film equivalent focal length of approximately 29-240 mm in a compact and lightweight design that measures approximately 84.5 mm and weights approximately 310 g. In addition, the lens' built-in IS provides 4.5 stops² of stabilization, and when paired with the EOS R7 camera, the lens IS and camera in-body image stabilization (IBIS) work in conjunction to provide up to 7.0 stops of IS². What's more, the lens is equipped with “Dynamic IS” that provides additional stabilization when recording video, and has a minimum autofocus distance of 0.17 m and close-up shooting with a maximum magnification of 0.44 x³, thereby expanding the range of users’ visual expression.
