Overview
The new Professional EF 24-70mm f/4L IS USM is a high performance, high flexibility, Hybrid IS Lens. The EF 24-70mm f/4L IS USM is the latest addition to Canon’s L-series lens line. With this lens Canon expanded the range of standard zoom EF lenses available for both professional and amateur photographers. Intended for reportage and wedding photography, it blends a very popular focal range with a high quality L-series lens design, ensures consistently sharp, professional quality stills in different situations. In addition, a new macro function, allowing it to shoot at a maximum magnification of 0.7x, that enables photographers not to carry a dedicated macro lens.
Its optical design incorporates two aspherical elements alongside two Ultra-low Dispersion (UD) lenses, each with optimised Super Spectra Coatings to reduce chromatic aberration, colour blurring and flare. Addition of constant f/4 aperture capability throughout the zoom range benefits photographers with exceptional creative control, achieving blurring of the background of a scene at all focal lengths. A nine-blade circular iris also helps photographers to make their main subjects stand out, delivering beautiful out of focus bokeh effects in the background blur to add artistic environment to a shot.
The EF 24-70mm f/4L IS USM also features a newly designed IS system to deliver blur-free images throughout the zoom range. This new optical IS offers a 4-stop light advantage. It’s Hybrid IS effectively manages angular and shift shake during macro photography for stable close ups.
Ultra fast AF is achieved by a small, ring-type Ultrasonic Motor (USM). In combination with a high-performance CPU and advanced AF algorithms, USM technology enables precise silent and super responsive autofocusing. Full-time manual focusing also provides manual adjustments can be made even when AF is engaged.
The EF 24-70mm f/4L IS USM lens incorporates top grade, usability-focused construction, both inside and out. The exterior surface has a high quality leather-texture coating, a revised shape helps ease of use, and the focusing and zoom rings have been optimized for optimal operation. In addition, a dust and drip-proof design is resistant to dust and moisture. A built in lock function prevents lenses from knocks when travelling. The fluorine coating minimises the degree of dust, dirt and fingerprints that adhere to the front and rear lenses to maintain superior image quality. Also check EF 24-70 f/2.8L II.
