Canon’s First Stabilised f/2.8L Trinity Lenses Launched for EOS-R Cameras

The EOS-R family of full-frame mirrorless cameras has got a lot more serious with the launch of the RF24-70mm f/2.8L IS USM and RF15-35mm f/2.8L IS USM zoom lenses.

Both sporting 5-stop CIPA-standard image stabilisation (IS) and a constant f/2.8 aperture, the 24-70mm and 15-35mm lenses are versatile and adept for professional applications.

Dual Sensing IS monitors both shake from the CMOS sensor and the lens’ gyro sensor that now allows the lens correct with precision for low-frequency shake like that caused by breathing.

The ultra-wide zoom range on the 15-35mm, a tad wider from the usual 16-35mm standard, lends itself to a wide variety of scenes from landscape to weddings, while the 24-70mm has come to be the standard zoom range perfect for every situation. For portraits, the 24-70mm delivers delightful circular bokeh with nine rounded aperture blades. 

Benefiting from the large diameter RF mount and proximity to the sensor, the lenses tout great resolving power from edge to edge by reducing refractions.

Aberrations are also reduced with the use of three aspherical lens elements and three ultra-low dispersion (UD) elements on the RF15-35mm f/2.8L IS USM, and two UD elements on the RF24-70mm f/2.8L IS USM. 

The Air Sphere Coating (ASC) further reduces flaring and ghosting caused by oblique light rays entering the lens, further diminishing optical performance.

The first two of the RF-mount trinity zoom lenses, the 15-35mm and 24-70mm deliver Nano USM in addition to image stabilisation. This means ultra-fast and smooth autofocus action for both stills and video.

Marked by the iconic red ring denoting their status as L-series lenses, the 15-35mm and 24-70mm lenses deliver water and dust resistance. Fluorine coating on the front and rear elements protect the lens by repelling water and oil stains.

With a focus on user-friendliness with a customisable tactile control ring that can independently adjust the ISO, shutter speed, aperture or exposure compensation – all with precision.

Pricing and availability of the RF15-35mm f/2.8L IS USM and the RF24-70mm f/2.8L IS USM will be announced at a later date.

The third lens in the trinity, likely a 70-200mm, is expected to be made available soon.
