Canon EF 200-400mm f/4L IS USM Extender 1.4X White Camera Lens - 576B002
Designed to satisfy the discriminating needs of sports and wildlife photographers,
the EF 200-400mm f/4L IS USM Extender 1.4X is a high-performance super telephoto
zoom lens with an optically matched built-in 1.4x extender for maximum versatility.
With a simple flick of a switch, the zoom range can be quickly increased to
280-560mm (f/5.6). This capability is extremely useful in applications where
it is not possible to change lenses quickly, while also protecting delicate
equipment such as a digital SLR camera's image sensor in environments with dust
and high humidity. The EF 200-400mm f/4L IS USM Extender 1.4X incorporates one
fluorite and four UD lens elements, which provide excellent correction of chromatic
aberration throughout the entire zoom range for professional quality images
with high resolution, contrast and color fidelity, while a 9-blade circular
aperture helps deliver beautiful, soft backgrounds. It utilizes inner focusing,
ring USM, a high-speed CPU and optimized AF algorithms for fast and accurate
autofocusing. And, with Power Focus mode, focus shifts are quiet and smooth,
which is essential for filmmaking. Image stabilization is effective up to four
shutter speed steps, with three image stabilization modes (standard, panning,
and during exposure only) providing excellent results for a wide range of subjects.
Optimized lens placement and coatings deliver outstanding color balance, while
helping to minimize ghosting and flare. The lens is highly resistant to dust
and water, enabling shooting even in harsh conditions. A fluorine coating on
front and rear lens surfaces repels dust particles and makes the lens easier
