Description — Canon 24-240mm f/4-6.3 IS USM
The Canon RF 24-240mm F4-6.3 IS USM is a full-frame zoom lens for Canon RF-mount mirrorless cameras, offering a focal length range from 24mm to 240mm — a span that covers wide-angle, standard, and telephoto perspectives in a single optic. The variable maximum aperture runs from f/4 at the wide end to f/6.3 at 240mm, which is typical for lenses of this zoom range. Built-in Optical Image Stabilization helps manage camera shake, particularly useful at longer focal lengths where shake is amplified.
The lens supports both autofocus and manual focus, giving photographers flexibility across different shooting scenarios. A 72mm filter thread makes it simple to attach widely available filters for exposure control or creative effects. The lens weighs 750 grams, balancing its broad focal range against everyday portability.
Designed specifically for the Canon RF mirrorless ecosystem, it is well suited to photographers who want one versatile lens for travel, events, or general photography without carrying multiple optics.
