EF 24-70mm f/4L IS USM and EF 35mm f/2 IS USM

Canon has introduced two new lenses to its range:
•  EF 24-70mm f/4L IS USM
•  EF 35mm f/2 IS USM

EF 24-70mm f/4L IS USM

•  high image quality 24-70mm lens with f/4 aperture
•  lightweight design
•  built-in IS
•  macro function
•  dust / moisture resistant

This lens combines an essential everyday focal range with a premium quality L-series construction. A new macro function optimises the placement of lens groups during close-up photography, allowing shooting at a maximum magnification of 0.7x.

The optical system includes two aspherical elements alongside two Ultra-low Dispersion (UD) lenses, each with optimised Super Spectra Coatings to minimise chromatic aberration, colour blurring and flare. A nine-blade circular iris delivers beautiful out-of-focus highlights (bokeh).

The EF 24-70mm f/4L IS USM also features a newly designed IS system. The advanced optical IS offers a 4-stop light advantage, while Hybrid IS effectively compensates for angular and shift shake during macro shooting for stable close ups.

Superfast AF performance is provided by a small, ring-type Ultrasonic Motor (USM). Working in combination with a high-performance CPU and advanced AF algorithms, USM technology enables accurate, silent and ultra-responsive autofocusing. Full-time manual focusing also ensures adjustments can be made even when AF is engaged.

A dust and drip-proof construction is resistant to dust and moisture, a lock function protects lenses from knocks when travelling, while fluorine coating minimises the amount of dust, dirt and fingerprints that adhere to the front and rear lenses – helping to reduce the need for cleaning.

EF 35mm f/2 IS USM

•  fixed prime 35mm wide angle lens
•  4-stop Image Stabilizer
•  fast f/2 minimum aperture
•  compact size and design
•  circular aperture

This is Canon’s first 35mm prime lens to feature optical Image Stabilizer technology, giving a 4-stop advantage. Intelligent detection of panning motion is supported, with Panning IS mode automatically engaged.

The EF 35mm f/2 IS USM features an aspherical glass-moulded (GMo) element positioned at the rear of the optical path to correct aberrations for the entire optical system. Additionally, each individual element features optimised Super Spectra coatings to reduce ghosting and flare – ensuring excellent colour balance with minimal need for post processing. A combination of a ring-type USM and high performance CPU  provides rapid AF performance, with full-time manual focus also available for users who want to retain maximum control.

New lens caps
Both new lenses come with newly-designed Mark II lens caps. These incorporate a hook mechanism in the centre of the cover, as opposed to the sides. Simply pinching the hook allows users to quickly remove and replace caps mid-shoot, especially when using lens hoods. The re-designed lens caps will start to be rolled out across Canon’s entire EF lens range from the beginning of January 2013 and will also be available to buy separately.
