Canon EF 24-70mm f4L IS USM Standard Zoom Lens: The EF 24-70mm f/4.0L IS USM Standard Zoom Lens from Canon is optimized for full-frame 35mm sensors, and another entry into Canon's high quality L-series of lenses. It has two Super Ultra-low Dispersion (Super UD) and two standard UD lens elements working together to lessen chromatic aberrations, and decrease colour blurring around the edges of your subject. Its two types of aspherical elements combine to help reduce spherical aberration over the complete image area and the full zoom range. Optimized lens coatings help make sure exceptional colour rendering while minimizing ghosting.
The EF 24-70mm f/4L IS USM is the perfect zoom to complement full-frame DSLRs like the EOS 6D. With 2 aspheric and 2 UD elements, the EF 24-70mm f/4L IS USM delivers high- quality images with excellent detail throughout the entire zoom range. A 9-blade circular diaphragm delivers beautiful, soft backgrounds. It offers a minimum focusing distance of 1.25 ft./0.38m across the entire zoom range and has a macro mode at the telephoto end with up to 0.7x magnification (minimum focusing distance becomes 7.87 in./0.2m) and is easily accessible with a one-touch switch. It features a Hybrid IS system with up to 4 stops of stabilization, compensating for both angular and shift types of camera shake, delivering effective stabilization even in macro. Inner focusing and ring-type USM deliver, fast, quiet AF, and full-time manual focus is available for manual focusing even while in AF mode. The durable EF 24-70mm f/4L IS USM is sealed for excellent dust and water resistance plus has fluorine coating on the front and rear an element reducing smears and fingerprints. Compact and lightweight, itís the perfect L-series lens for photographers on the go.
Featuring dynamic L-series optical performance in a compact, lightweight and sturdy design, the new EF 24Ė70mm f/4L IS USM lens is well suited for all levels of advanced photography on the go. The ideal companion to Canonís full-frame Digital SLR cameras such as the EOS 6D, the lens features a constant maximum aperture of f/4 throughout the entire zoom range with 15 lens elements in 12 groups including two aspherical and two UD lens elements and a 9-blade circular aperture diaphragm. The EF 24Ė70mm f/4L IS USM lens delivers gorgeous images with outstanding detail at all focal lengths and includes a macro feature at the telephoto end with a 0.2m/7.9-inch minimum focusing distance and Canonís Hybrid IS system (with up to four stops of stabilization). The macro feature can be engaged through a switch on the lens barrel. Additionally, the lens features inner focusing and a ring-type Ultrasonic Motor (USM) for quiet, fast autofocus, and has full-time mechanical manual focus thatís enabled even during AF operation. Compact at only 93mm in length, with brilliant dust and water resistance, the EF 24Ė70mm f/4L IS USM lens has a fluorine coating on the front and rear elements for easy maintenance and cleaning.
Its ring-type Ultra Sonic Motor (USM) and high-speed CPU, with optimized AF algorithms, ensure you experience quick, quiet and precise auto focusing whenever you need it. The lens has improved dust and water resistance to protect it from damage outdoors, while fluorine coatings on the front and rear lens surfaces resist fingerprints and smearing. The circular nine-bladed diaphragm delivers beautiful, soft background effects. A zoom lock lever holds the zoom position at the 24mm wide end for safe transporting while attached to an EOS DSLR camera over the shoulder - preventing lens creep.
Introducing image stabilization to their 24-70mm L-series lenses, Canon's Hybrid IS provides four stops of effective shutter speed compensation for both types of camera shake when shooting macro photography: angular and shift. This means you can shoot in dimmer conditions, capturing images with shutter speeds up to four stops slower than would otherwise be possible.
