Product Description
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
to clean.
