Canon RF 10-20mm f4 L IS STM ultra-wide-angle lens introduced

Canon has unveiled the RF 10-20mm f4 L IS STM, a cutting-edge full-frame RF-mount L-series ultra-wide-angle lens tailored for professional photographers and dedicated enthusiasts. Notably, this lens boasts a remarkably lightweight design, weighing in at a mere 570 grams, approximately half the weight of its predecessor, the EF 11-24mm f4 L lens.

Canon’s innovative engineering techniques are evident in this lens. By strategically positioning the rear lens element closer to the sensor, Canon has achieved a smaller front element, enhancing the directness of the light path and reducing aberration significantly.

One of the standout features of the RF 10-20mm f4 L IS STM is its Image Stabilization (IS) technology, effectively minimizing wide-angle distortion at the outer edges of the frame. Additionally, videographers will appreciate the lens’s quiet STM focus drive, ensuring smooth and unobtrusive focusing during video recording.

Moreover, the lens comes equipped with practical elements such as a built-in lens hood, a rear gelatin filter holder, and a convenient Fn function button on the body for seamless adjustments of settings.

In terms of optics, the lens boasts a sophisticated configuration, comprising 16 elements in 12 groups. Noteworthy elements include 1 Super UD lens, 2 UD lenses, 1 UD aspherical lens, and 2 aspherical lenses, all contributing to exceptional image quality.

The lens features a 9-blade aperture, fluorine coating on both front and rear elements, and a robust dust and water-resistant design, ensuring durability and reliability in various shooting conditions.

Price and release date

Enthusiasts can now pre-order the Canon RF 10-20mm f4 L IS STM lens on and for $2,299, with availability starting from November 2, 2023.
