Canon has announced it is developing the EF 200-400mm f/4L IS USM Extender 1.4x lens, which features a built-in switchable 1.4x teleconverter. With the converter engaged, it becomes a 280-560mm F5.6 lens. Designed for sports and wildlife photographers the lens will feature weatherproof construction and is scheduled for launch later this year.

Cheers
