Canon RF 10-20 mm f/4L IS STM: super ultrangular imaging on a compact objective

Canon has developed the RF 10-20mm f/4L IS STM lens, a new addition to the L-series for professionals that allows you to capture super ultra-wide images with unparalleled image quality, all in a compact size.

This new lens, which builds on the features already found in current RF wide angle lenses, offers an ultra-wide autofocus zoom for full frame cameras, with a viewing angle up to 130°. With a zoom that covers from the 20mm wide angle up to an exceptional and unique ultra focal length 10mm wide angle, users can now achieve more than twice the shooting area of ​​a 16mm focal length.

Thanks to this, more can be included in the frame, which enables new perspectives when trying to capture high-impact panoramas. Photographers will be able to add more interest to the foreground, capture smaller interiors and architectural structures, and add depth to landscapes, while filmmakers can get more creative with impressive long shots.

The RF 10-20 mm f/4L IS STM incorporates the most advanced technology of Image Stabilization (IS) of Peripheral Control, which ensures extremely clear, motion-free images even in the most challenging shooting conditions, even without using a tripod.

The new image stabilization (IS) ensures blur-free images from the center to the edges and offers five steps of optical stabilization or up to six stops in combination with a camera with in-body stabilization. His rectilinear optical design Advanced allows you to achieve sharp and precise results, so that straight lines remain straight, even towards the edges of the frame.

They are maximum aperture f/4 Constant lensing provides consistent exposures for any zoom setting, while more advanced optical coatings minimize ghosting and ghosting, which often occurs in ultra-wide shooting.

Ultracompacto

Advanced technology does not mean reducing ease of use. The RF mount allows you to achieve extraordinary image quality in a compact design by offering much faster communication speed as well as greater bandwidth between the camera and lens.

Con only 570 grams, is less than half the weight (610 grams lighter) and is 2 cm smaller in diameter and length than the EF 11-24 mm f/4L USM. In fact, the new lens mounted on the EOS R8 weighs less than the old EF lens alone. And all this by offering a greater angular angle of view, in addition to incorporating a new IS technology, so that shooting in smaller spaces is not only easier, but also so that you are less burdened.

The new lens is capable of withstanding even the more difficult atmospheric conditions, since it is resistant to dust and humidity, so that professionals can use it safely.

Lastly, highlight that it has SWC coatings (on 2 lens surfaces) and ASC (Air Sphere Coating) that reduce ghosting caused by light sources in the image, a phenomenon often seen with wide-angle lenses. Besides incorporates an STM engine with the ability to focus manually at all times, thanks to a lightweight and compact focusing lens group
