Canon has announced a new ultra-wide angle lens for the EOS R mirrorless camera system. The first L-series lens to feature a Stepping Motor (STM), the RF 10-20mm f4L IS STM offers the widest angle yet for the RF mount (bar the specialist Dual fisheye lens) along with near-silent operation.
Taking its cue from the professional EF 11-24mm f4L USM lens, this new design shaves 2cm in length and width off the dimensions, as well as more than 50% of the weight. Coming in at 570g, the RF 10-20mm f4L IS STM lens is compact and easily handholdable even for challenging conditions, thanks to the latest Peripheral Control Image Stabilisation (IS) technology and 5-stop optical image stabilisation, which increases to 6 stops when combined with a camera with in-body image stabilisation (IBIS).
The optical design of the lens overcomes the potential problems of such wide angle focal lengths, with the use of Ultra-low Dispersion (UD), Super UD and GMo aspherical lenses, plus various lens coatings to reduce ghosting, flare and optical distortion. The lens also has an advanced rectilinear optical design so that straight lines are capturing straight, even at the edges of the frame.
Designed for professional use, the new RF 10-20mm lens is also dust- and moisture-resistant.
The RF 10-20mm f4L IS STM lens will be available from the end of October 2023 with an RRP of £2,579.99 / €2,939.99.
