Canon today adds to its world-famous EF lens series with the launch of three
new lenses for photography professionals and enthusiasts.
The new EF 24-70mm f/2.8L II USM professional zoom lens is an update
to the popular EF 24-70mm f/2.8L USM, while the new EF 24mm f/2.8 IS USM
and EF 28mm f/2.8 IS USM are the world’s first¹ wide-angle prime lenses
to feature optical Image Stabilizer (IS) technology. All three provide
the highest levels of performance for modern digital photographers,
combining premium image quality with durable, user-friendly designs.

EF 24-70mm f/2.8L II USM: the ultra-high performance standard zoom
The new EF 24-70mm f/2.8L II USM features completely redesigned optics
to provide outstanding clarity, image quality and durability. A compact
design makes it ideal for carrying on every shoot, and a range of
optical enhancements provide improved performance - capturing greater
detail across the frame while reducing distortion throughout the entire
zoom range, particularly at the maximum 70mm focal length.
With a redesigned optical system that includes two Ultra-low Dispersion
(UD) and one Super UD aspheric elements to minimise chromatic aberration
and colour blurring, the lens delivers consistently sharp, high-contrast
images. Each lens element also features Canon’s optimised Super Spectra
coatings to reduce ghosting and flare and ensure excellent colour
balance. Additionally, a fluorine coating minimises the amount of dust,
dirt and fingerprints that adhere to the front and rear of the lens,
helping to maintain superior image quality.
The EF 24-70mm f/2.8L II USM also enables photographers to capture their
subjects up close, with a minimum focusing distance of 0.38m at all
focal lengths throughout the zoom range. A ring-type Ultrasonic Motor (USM)
works in combination with a high-performance CPU and advanced AF
algorithms to ensure accurate, silent and ultra-responsive autofocus.
For those who prefer to maintain full control in every shot, full-time
manual focusing allows photographers to precisely tweak or alter the
focus of their shot at any time, even when AF is engaged.
Distinguished L-series design
The EF 24-70mm f/2.8L II USM is the latest lens from the elite L-series
to offer Canon’s high-grade and user-focused design enhancements. The
mechanical structure of the lens has been improved to offer enhanced
zoom durability and greater shake and shock resistance within the lens
barrel. The size of the lens has also been reduced by 10mm compared to
the previous model, providing enhanced portability and greater
convenience in everyday use. A new Zoom Lock lever also enables
photographers to lock the zoom position at the extreme wide end to
prevent damage to the lens in transit, while a water and dustproof
construction² enables users to continue shooting in harsh conditions.
Introducing the world’s first wide-angle primes with IS
Canon today also launches the new EF 24mm f/2.8 IS USM and EF 28mm f/2.8
IS USM - the world’s first 24mm and 28mm fixed wide-angle lenses to
feature optical IS technology. Ideal for landscape and reportage, both
lenses offer outstanding flexibility allowing photographers to shoot an
even broader range of scenes and subjects - combining fast apertures
with IS to enable sharp results when shooting handheld, even in low
light conditions.
Offering an advantage of up to 4-stops over lenses without IS, both
lenses are ideal for capturing more of the scene thanks to their wider
focal lengths. Both feature a wide f/2.8 aperture, allowing
photographers to explore shallow depth of field, or to shoot in
lower-light conditions. Wide apertures and IS technology also make each
lens ideal for shooting fast-moving subjects, while Canon’s advanced IS
technology is able to detect intentional panning movement and
automatically switch from Normal IS mode to Panning IS mode - helping
users to capture movement with greater accuracy.
Silent, high-speed AF performance is provided by the inclusion of a
ring-type USM and additional features including optimized AF control.
Full-time manual focusing also ensures adjustments can be made even when
AF is engaged, while a minimum focusing distance of 0.20m (EF 24mm f/2.8
IS USM) and 0.23m
(EF 28mm f/2.8 IS USM) allows photographers to get even closer to
smaller or more detailed subjects.
Designed to perform
Both the EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM feature
redesigned optics to improve image quality and reduce the need for
post-production. An aspherical glass moulded (GMo) lens element is
incorporated to correct aberration throughout the optical system, while
Canon’s optimised Super Spectra Coatings reduce ghosting and flare for
stand-out image quality. Externally, both models also boast a number of
design similarities with Canon’s professional L-series lenses, with a
similar coating on the barrel and a similar design on the focus ring. A
distance scale is also included to assist with landscape photography,
while the compact design makes these lenses an unobtrusive addition to
any kit bag.
