New from Canon

A very innovative design with built in multiplier.

The Canon  new EF 200-400mm f/4L IS USM Lens with built in 1.4x Extender is here.

Canon had shown this new lens earlier this year, and has finally announced the availability of the EF 200-400mm f/4L IS USM lens with a built in 1.4x Extender.
I just love the white  lens barrels; it may be one of the  irrational reasons why Canon has had so much success lately.

This lens has a very unique design, as you can increase the effective focal length so that it becomes a 280mm to 560mm lens with a flick of a switch that enables built in optics that act as a 1.4x Teleconverter. When using on a camera with an APS-C size sensor versus a 35mm size sensor, the effective focal length will become even longer (equivalent to a 320-640mm lens without the extender turned on, or equivalent to a 448-896mm lens with the extender enabled). That's a serious focal range for a zoom lens with its light gathering ability.

This is a premium quality lens including the latest optical advances like use of both Fluorite and Ultra-Low Dispersion lens elements to reduce Chromatic Aberrations, with the latest Lens coatings to help minimize any flare and ghosting in harsher lighting.
As for the price, no announcement yet but it will be high.
