With a focal length ranging from 24 mm at the wide end to 240 mm at the telephoto end, the 10x optical zoom of the RF24-240mm F4-6.3 IS USM covers a versatile range of scenes including travel, snapshot, landscape and portrait photography. What’s more, the RF24-240mm F4-6.3 IS USM achieves significant image stabilization equivalent to approximately 5 shutter-speed stops¹.

Thanks to the wide diameter and short back focus² that characterize the RF mount, the rear lens group (the lens group closest to the camera’s sensor) of the RF24-240mm F4-6.3 IS USM can accommodate a larger lens that makes possible greater image quality from the center to the periphery while still retaining a compact and lightweight design. In addition, the use of UD³ and aspherical lenses help realize higher image quality by reducing a variety of aberrations.

The RF24-240mm F4-6.3 IS USM also utilizes Canon’s proprietary Nano USM, an ultrasonic motor that enables improved autofocus speeds. The combination of this technology with Dual Pixel CMOS AF used by EOS R system cameras makes possible autofocus performance that is fast and precise when capturing still photos and smooth during video shooting.
