With the RF 10-20mm f/4 L IS STM, Canon has defined the professional ultra-wide-angle zoom lens. Wide angle of view, small in size and equipped with more functions than its competitors - this lens offers photographers and filmmakers the performance they need to realise their creative ambitions. The image stabiliser with peripheral control, which is effective right into the corners of the image, offers protection against camera shake up to five exposure stops (six exposure stops when using EOS cameras with in-camera image stabilisation) and ensures steady video footage. Integrated lens hood, STM motor.
