These are the three key lenses every pro camera system needs these days: a constant aperture f/2.8 standard zoom, a constant f/2.8 ultra-wideangle zoom and a 70-200mm f/2.8 telephoto zoom. And today Canon officially announced two out of those three key lenses.

The two new lenses are the Canon RF 24-70mm F2.8L IS USM standard zoom and the Canon RF 15-35mm F2.8L IS USM. The only one still to come is the RF 70-200mm F2.8L IS USM which is due to arrive later in 2019.

These lenses closely follow the arrival of the RF 24-240mm F4-6.3 IS USM superzoom and the impressive RF 85mm F1.2L USM portrait lens – and there’s an RF 85mm F1.2L USM DS version of this lens to arrive later in 2019. It's all part of the Canon RF lens roadmap announced earlier in 2019.

Canon RF 15-35mm F2.8L IS USM

The RF 15-35mm F2.8L IS USM is Canon’s widest lens yet for the EOS R system, and its widest lens ever with an f/2.8 maximum aperture – though the EF 16-35mm f/2.8 is only a millimetre out, so it’s not a massive leap forward. 

More importantly, this is the first Canon ultra-wide f/2.8 L-series lens with Canon’s 5-stop image stabilization system, offering Dual sensing IS and Combination IS.

The optical configuration includes two ultra-low dispersion elements and three moulded glass aspheric elements and is designed to correct aberration, distortion and astigmatism

This and the new RF 24-70mm F2.8L IS USM are the first fast-aperture Canon zoom lenses with Nano USM autofocus technology, which combines high-speed AF for stills photography with continuous, smooth, virtually silent focusing for video.

Like other RF lenses, this one has a customisable control ring which can be used for aperture adjustments, shutter speed, ISO or EV compensation. The RF 15-35mm F2.8L IS USM is sealed against dust and moisture (another L-series lens characteristic) and uses Canon’s SWC (Sub wavelength structure Coating) and ASC (Air Sphere Coating) to counteract flare and ghosting. There’s a fluorine coating on the front element, too, to repel oil and water.

The Canon RF 15-35mm F2.8L IS USM will be available September 2019 at a price of $2,299 / £2,329.99.

Canon RF 24-70mm F2.8L IS USM

The Canon RF 24-70mm F2.8L IS USM is designed as a high-performance standard zoom for pros. It joins the Canon RF 24-105mm F4L IS USM, which is more of a long-zoom kit lens, and the big and exotic Canon RF 28-70mm F2L USM, which is a stop faster and has a slightly shorter zoom range and – crucially – no image stabilizer.

Like the RF 15-35mm F2.8L IS USM, the RF 24-70mm F2.8L IS USM is the first fast-aperture Canon zoom with Nano USM, a new autofocus actuator system that offers the torque needed for fast AF focus for stills, but the smooth, near silent focus adjustments needed for video. Video is clearly high on Canon’s list of priorities now, as the new 24-70mm has been designed to suppress ‘focus breathing’ – small changes in magnification as a lens focuses. Focus breathing barely shows up in stills photography, but it can be visible in video.

As usual with RF lenses, the RF 24-70mm F2.8L IS USM has a customisable control ring for adjusting the lens aperture, shutter speed, ISO or EV compensation. It’s also dust and moisture sealed, like other L-series lenses, comes with Canon’s ASC (Air Sphere Coating) and has an oil and water-repellent fluorine coating on the front element.

The Canon RF 24-70mm F2.8L IS USM will be available from September 2019 at a price of $2,299/ £2,329.99.

SPECIFICATIONS

Focal length: 24-70mm
Construction: 21 elements in 15 groups
Maximum aperture: f/2.8
Minimum aperture: f/22
Aperture blades: 9
Minimum focusing distance: 0.21/0.38m

Firmware updates for the EOS R and RP

At the same time as announcing its new RF lenses, Canon has promised a firmware update for the Canon EOS R and EOS RP, due to arrive before the end of September 2019. 

The update will enhance the eye detection AF performance on both cameras, so that it works at much greater subject distances, acquires focus faster, offers improved accuracy and tracking and brings ‘simplified’ Eye AF Tracking indicators.
