In addition, when used with an APS-C format camera, it is equivalent to a 16-32mm focal length angle of view, which is the classic focal length of a wide-angle zoom lens.

According to the editor’s understanding, this lens uses an optical structure of 16 elements in 12 groups, including 1 UD aspherical lens, 2 UD lenses, 2 The aspherical lens and 1 super UD lens also use SWC sub-wavelength structure coating (2 sides) and ASC coating (2 sides), which effectively suppresses flare and ghosting that are prone to occur with wide-angle lenses.

RF10-20mm F4 L IS STM lens has an anti-shake effect of up to 5 levels. It adopts a 9-blade circular aperture. The maximum aperture is always maintained at F4. Recently, Focusing distance is approximately 25cm. In addition, this lens introduces peripheral coordination control for the first time, working together with camera models that support body image stabilization, to more effectively compensate for previously difficult-to-compensate peripheral shake of the image

Canon RF10-20mm F4L IS The STM lens is also equipped with a lead screw type STM stepper motor.
