Canon continues to pump out quality glass for its mirrorless range of camera bodies, today releasing its widest RF zoom to date.
Canon Australia has announced the RF 10-20mm f/4L IS STM, boosting the L-series range for photo and video professionals. The angle of view opens up to a massive 130° and the results speak for themselves. The RF 10-20mm f/4L IS STM is a rectilinear lens so lines are straight, even at the edges.
This is definitely not a fisheye lens.
Yes it is f/4, but with 5-stops of built-in stabilisation and autofocus I think it’s a winner. In fact, the IS goes up to 6-stops when combined with the in-body stabilisation. I think everyone would love a faster lens but at least it’s f/4 throughout the zoom range. This helps with consistent exposure at every zoom setting. Also, optical coatings minimise ghosting and flare which can be common with ultra-wide shots.
The video below from Canon USA gives you a great idea of the lens’ capability.
It’s also pretty small and light for a lens of this quality and complexity. Weighing just 570g, the RF 10-20mm f/4L IS STM is ideal for travel.
Canon makes the point that it’s less than half the weight (610g lighter) and 2cm smaller in width and length than the EF 11-24mm f/4L USM – in fact, the new lens paired with an EOS R8 weighs less than the older EF lens alone.
- The aspherical, Super UD, and UD lens elements (including one Aspherical UD element)
which help to achieve high image quality appropriate for an L lens
- Highly durable dust and water resistant qualities, to withstand rigorous conditions faced by
- SWC (on 2 lens surfaces) and ASC (Air Sphere Coating) reducing 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
