The L-series lens has an integrated 1.4x focal length extender and high‐performance Image Stabilization technology.
The lens features an optically-matched, built-in 1.4x extender that increases the maximum focal length to 560 mm, but preserving image quality, says Canon. With a simple switch, photographers can easily increase zoom range.
To help deliver beautiful soft image backgrounds, the lens features a 9-blade circular aperture.
The lens also utilizes inner focusing, ring USM, a high-speed CPU, and optimized AF algorithms for fast and accurate autofocusing.
Quiet and smooth focus shifts – essential for filmmaking – are made possible with Canon’s Power Focus mode.
Using advanced optical materials such as fluorite crystal and UD glass, Canon says the lens provides excellent correction of chromatic aberration throughout the entire zoom range, and delivers high-quality images with high levels of resolution, colour fidelity and contrast.
It also offers three image stabilization modes – standard, panning, and during exposure only – and stabilization effective up to four shutter speed steps.
The lens also includes dust- and water-resistant construction designed for extended usage under harsh conditions.
The EF 200-400 mm f/4L IS USM Extender 1.4x zoom lens is expected to be available at the end of May for an estimated retail price of $12,399.99.
