MTF charts for EF24-70 4 l IS

A quick guide to MTF charts (which only measure contrast and resolution. Canon's guide to their MTF charts) Black lines reflect lens performance at widest aperture. Blue lines show the performance at f/8 Thick lines indicate lens contrast Thin lines indicate lens resolution Dashed lines: Lens performance with meridional lines. Solid lines: Lens performance with sagittal lines Closer sagittal and meridional chart lines indicate more 'natural' out of focus areas. Remember that MTF charts are good for comparing similar lenses, so comparing ones from the 14mm f2.8L and 300mm 2.8L won't tell you much at all, whilst comparing the EF14 2.8L with the EF14 2.8L II will show meaningful differences. Note that other manufacturers may have different ways of displaying such information that may or may not match up with the Canon figures.

Product launch - press info includes EF35/2

United Kingdom, Republic of Ireland, 6 November 2012 – Canon today adds to its world-famous EF lens series with the launch of two models designed for enthusiasts and professionals – the EF 24-70mm f/4L IS USM and EF 35mm f/2 IS USM. Offering first-class optical technologies alongside highly compact designs, the new lenses are perfect for a range of creative purposes, including reportage, landscape, portrait, and travel photography.

Ideal for use alongside DSLRs like the new EOS 6D, both new lenses utilise the latest Canon technologies to consistently deliver superb results. Both include aspherical lenses and Super Spectra Coatings optimised for each individual element, Canon’s industry-leading Image Stabilizer (IS) technology and Ultrasonic Motors for superfast Auto Focus (AF) – providing outstanding optical performance.

The EF 24-70mm f/4L IS USM is also the latest lens to feature Hybrid IS, delivering shake-free shots at any distance, including at macro focal lengths.

EF 24-70mm f/4L IS USM – high performance, high flexibility, Hybrid IS

The EF 24-70mm f/4L IS USM is the latest addition to Canon’s elite L-series, and expands the range of standard zoom EF lenses available for both professional and amateur photographers. Ideal for reportage and wedding photography, it combines an essential everyday focal range with a premium quality L-series construction, delivering consistently sharp, professional-quality stills in a range of different situations. A new macro function also optimises the placement of lens groups during macro photography, allowing shooting at a maximum magnification of 0.7x – reducing the need for photographers to carry a dedicated macro lens.

Its first-class 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 constant f/4 aperture throughout the zoom range provides photographers with exceptional creative control, allowing blurring of the background of a scene at all focal lengths. A nine-blade circular iris also assists photographers in making their subjects stand out, delivering beautiful out of focus highlights (bokeh) in the background blur to add atmosphere to a shot.

The EF 24-70mm f/4L IS USM also features a newly designed IS system, delivering blur-free images throughout the zoom range. Canon’s 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.

The EF 24-70mm f/4L IS USM features a high grade, usability-focused design – both inside and out. The exterior features a high quality leather-texture coating, a revised shape ensures ease-of-use, and the focusing and zoom rings have been designed for optimal operation. Additionally, 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 maintain superior image quality and reduce the need for cleaning.

EF 35mm f/2 IS USM – take a wider look at the world

The new EF 35mm f/2 IS USM is designed to offer outstanding flexibility – allowing photographers to capture an even broader range of scenes and subjects in wide-angle. The lens is Canon’s first-ever 35mm prime to feature optical Image Stabilizer technology, which combines with high quality optics to offer outstanding performance from a lightweight, compact body. The 35mm focal length also provides the ability to capture everything from close-up portraits to wide-angle landscapes, making it an ideal companion for travel or general reportage photography.

Its advanced specification offers photographers great flexibility to shoot a wider-range of scenes and subjects. A bright, fixed f/2 aperture also allows photographers to employ a shallow depth of field, and optical IS offers users a 4-stop light advantage, allowing the capture of blur-free images in low light conditions when shooting handheld. Intelligent detection of panning motion is also supported, with Panning IS mode automatically engaged to enable photographers to capture movement with greater accuracy.

Designed to deliver exceptional image quality, the EF 35mm f/2 IS USM features an aspherical glass-moulded (GMo) element positioned at the rear of the optical path to correct aberration 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 also provides rapid AF performance, with full-time manual focus also available for users who want to retain maximum control.

New lens caps – designed for greater ease and convenience
Both new lenses also come with newly-designed Mark II lens caps, which 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.
