Canon EF 200-400mm f/4L IS USM Extender 1.4x Lens

Capture the Action with Canon EF 200-400mm f/4L IS USM Extender 1.4x Lens

The EF 200-400mm f/4L IS USM Extender 1.4x from Canon is a medium to super-telephoto distinguished by its unique optical design and fast performance. Featuring a built-in 1.4x extender, you can quickly and intuitively switch between the native 200-400mm f/4 setting and an effective 280-560mm f/5.6 for greater reach.

Benefitting this unique design is a sophisticated optical layout, which includes one fluorite element and four ultra-low dispersion elements to control chromatic aberrations and color fringing for increased clarity. A Super Spectra coating has also been applied to individual elements to reduce lens flare and ghosting for greater color accuracy and contrast when working in bright or backlit conditions.

• EF-Mount Lens/Full-Frame Format

• Built-In 1.4x Extender
• One Fluorite and Four UD Elements
• Super Spectra Coating
• Ring-Type Ultrasonic Motor AF System
• Optical Image Stabilizer
• Power Focus, Focus Limiter, Focus Preset
• Weather-Sealed Design, Fluorine Coating
• Detachable, Rotatable Tripod Collar

Beyond the optical attributes, this 200-400mm f/4 is also characterized by its advanced four stop-effective Image Stabilizer system, which has three separate stabilization modes to suit various shooting applications. Also complementing handling is a sophisticated ring-type USM, which provides quick, quiet, and accurate autofocus performance along with full-time manual focus override. Additionally, this lens is weather-sealed for use in trying environmental conditions and it has a removable rotating tripod collar to benefit working atop a tripod or monopod.

• Super telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 1280mm equivalent focal length.
• Relatively bright f/5.6 maximum aperture affords control over depth of field for isolating subjects and producing selective focus imagery.
• Two fluorite elements, along with one Super Ultra-Low Dispersion element and one ultra-low dispersion element, are used to greatly reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.
• Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.
• An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. In addition to the single-shot standard IS mode, a second mode is also available that it optimized for panning.
• A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
• A Focus Preset function is available to quickly recall a programmed focusing position.
• Focus Limiter switch lets you constrain the focusing to three different ranges to suit different applications: 19.7-65.6′, 19.7′-infinity, or 65.6′-infinity.
• Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
• As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
• Fixed rotating tripod collar benefits working with the lens atop a tripod or monopod.
• Compatible with optional EF 1.4X and EF 2X teleconverters.
