Canon previously announced their 200-400mm f4 L IS USM lens a while back, but it was then delayed for unknown reasons. Today, the company is re-announcing the lens with a 1.4x teleconverter built in–therefore extending its reach to 280â560mm (f/5.6) with what they’re saying is, “A flick of a switch.” They’re also touting that this will help with ensuring that dust doesn’t get into the camera’s electronics.
The EF 200â400mm f/4L IS USM Extender 1.4X incorporates one fluorite and four UD lens elements, a 9-blade circular aperture, features inner focusing, ring USM, a high-speed CPU and optimized AF algorithms. Plus it has a Power Focus mode that makes focus shifts quieter while filming.
Canon is also promising up to four stop of Image stabilization with either standard, panning, and during exposure only.
