Canon-200-400mm-lens-reviews Canon USA unveiled a super-telephoto zoom lens for use with all EOS DSLRs—the EF 200–400mm f/4L IS USM Extender 1.4x. Geared for sports and wildlife photography, the L-series lens has an integrated 1.4x focal length extender and Canon Image Stabilization technology.

It features an optically matched, built-in 1.4x extender that increases the maximum focal length to 560mm, “simultaneously preserving image quality and enabling the seamless capture of distant, moving subjects,” notes Canon. With one switch, photographers can increase zoom range, which is convenient when it’s difficult to change lenses quickly and also helps protect a DSLR’s image sensor in environments with dust, high humidity or other extreme environmental factors.

To help deliver soft image backgrounds, the lens employs a nine-blade circular aperture. It also uses inner focusing, ring USM, a high-speed CPU and optimized AF algorithms to provide fast, accurate autofocusing. Quiet, smooth focus shifts are also made possible with Canon’s power focus mode.

Other lens features include: the use of fluorite crystal and UD glass for correction of chromatic aberration throughout the entire zoom range; three image stabilization modes (standard, panning and during exposure only); and stabilization effective up to four shutter speed steps. The new lens also includes dust- and water-resistant construction designed for extended usage under harsh conditions.

With dust- and water-resistant construction, Canon’s EF 200–400mm f/4L IS USM Extender 1.4x zoom lens will be available at the end of May for an SRP of $11,799. usa.canon.com
