Canon Launches Three New Lenses
February 7, 2012 /Photography News/
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 --according to Canon research as of February 2012-- the world’s first 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.

Wide angle with IS is a nice compliment to their stable of pro lenses.
