Canon has announced the latest addition to its RF range, the RF 10-20mm f/4L IS STM. The RF 10-20mm lens is the widest lens from Canon, and it is claimed to provide superb image quality in a compact size.
Key features
- The aspherical, Super UD, and UD lens elements (including one Aspherical UD element) help to achieve high image quality appropriate for an L lens
- Highly durable dust and water-resistant qualities, to withstand rigorous conditions faced by professionals
- SWC (on 2 lens surfaces) and ASC (Air Sphere Coating) reduce ghosting caused by light sources within the image, a phenomenon often seen in wide-angle lenses
- First L series lens to feature STM motor and full-time manual focus capability, thanks to compact lightweight focus group
The RF 10-20mm f/4L IS STM incorporates the latest Peripheral Control Image Stabilisation (IS) technology which is claimed to allow users to capture crystal-clear, shake-free images even in challenging shooting conditions or without a tripod. The new IS helps produce shake-free images from center to the edge of the frame and offers five stops of optical stabilization or six stops in combination with an in-body stabilized camera. The rectilinear optical design means that straight lines remain straight, even at the edges of the frame. The lens also has optical coatings to help minimize ghosting and flare which can be common with ultra-wide shots.
The lens weighs 570g / 20.1 oz and it is less than half the weight (610g lighter) and 2cm smaller in width and length than the EF 11-24mm f/4L USM. The new lens paired with an EOS R8 weighs less than the older EF lens alone.
Pricing & availability
The Canon RF 10-20mm f/4L IS STM is expected to start shipping on November 2nd for $2,299 USD.
