Canon's new pro wide angle zoom lens


Canon have released EF 16-35 mm f/4L IS USM

The lens is a new professional ultra wide angle zoom with 4 stops of shake reduction. This means that it will be easier for photographers to get high quality videos when hand holding the camera. The lens has a new optical solution for better quality. It is also lighter and more compact than the older EF 16-35mm f/2.8L II USM. Retail price is set to $1199. I will probably get this, as I think it will complement my existing gear.

From Canon USA

"Fully compatible with all EOS Digital SLR cameras including full-frame models like the EOS 5D Mark III and EOS 6D Digital SLR cameras, the compact and lightweight EF 16-35mm f/4L IS USM ultra wide-angle zoom lens offers high image quality and an Optical Image Stabilizer (IS) for shake correction up to four shutter speed stepsii, making handheld shooting possible in dimly lit scenes where camera shake can occur. In addition, an intelligent CPU in the lens automatically selects the optimal IS mode by recognizing differences between normal handheld shots and panning. This technological advancement supports a greater range of creative expression for photographers in otherwise difficult shooting situations, such as dark indoor scenes where flash photography is prohibited, or in places where a tripod cannot be used, or when shooting at low ISO speeds.

The EF 16-35mm f/4L IS USM ultra wide-angle zoom lens features newly developed, high quality Canon optics that incorporate three GMo (Glass-Molded) aspheric lens elements, including a large-diameter aspheric lens, which help improve image quality by correcting aberrations. Two additional UD lens elements help reduce chromatic aberration from edge to edge throughout the entire zoom range for excellent image quality with high resolution and contrast. The lens also features enhanced fluorine lens coatings on the front and rear lens surfaces to repel dust particles and help ensure superb color balance while minimizing ghosting. The inner focusing and ring USM offer silent, fast and accurate autofocusing. Full-time manual focus adjustment is available in autofocus (AF) mode. A nine-blade circular aperture creates beautiful, soft backgrounds. A new compact four-group zoom system provides a minimum focusing distance of 0.28m/11 inches throughout the zoom range and a maximum magnification of 0.23x at the telephoto end for outstanding performance." - Canon USA
