Canon EF 24-70mm f/2.8L II USM, EF 24mm f/2.8 IS USM and EF 28mm f/2.8

Canon adds to its 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 first (according to Canon research as of February 2012) wide-angle prime lenses to feature optical Image Stabilizer (IS) technology.

• Fast f/2.8 maximum aperture
• Up to four-stop Image Stabilizer
• Ultrasonic autofocus mechanism
• Circular aperture for soft background blur
• Super Spectra coatings reduce flare

EF 28mm f/2.8 IS USM

EF 28mm f/2.8 IS USM key features

• 28mm wide-angle lens (45mm equivalent on APS-C sized sensors)
• Fast f/2.8 maximum aperture
• Up to four-stop Image Stabilizer
• Ultrasonic autofocus mechanism
• Circular aperture for soft background blur
• Super Spectra coatings reduce flare

Canon EF 24-70mm f/2.8L II USM

The new EF 24-70mm f/2.8L II USM features completely redesigned optics in a compact design that makes it ideal for carrying on every shoot.

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.

The lens has a minimum focusing distance of 0.38m at all focal lengths throughout the zoom range.

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. 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 construction (Waterproof construction around the lens mount, switch panel, zoom ring, focusing ring and zoom lock. Weatherproof when used with weatherproof EOS bodies) enables users to continue shooting in harsh conditions.

EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM Canon lenses

These 24mm and 28mm fixed wide-angle lenses offer up to 4-stops over lenses without IS. Both feature a wide f/2.8 aperture the 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.

The EF 24mm f/2.8 IS USM has a minimum focusing distance of 0.20m and the EF 28mm f/2.8 IS USM features a minimum focusing distance of 0.23m.

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.

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
