The EF 200-400mm f/4L IS USM Extender 1.4x features a flexible 200-400mm focal range with a fixed f/4 aperture, 4-stop optical Image Stabilizer and for the first time in a commercially available lens, a built-in 1.4x extender.

A robust magnesium alloy design, environmental protection and specialised lens coatings also make it ideal for mobile use, combining with the finest quality optics to deliver exceptional results, even in the harshest conditions. . . . read more

Canon EF 200-400mm f/4L IS USM with inbuilt 1.4 teleconverter hands-on review by Joshua Holko.

This is the second Canon lens to employ a built-in converter, after the FD 1200mm f5.6 that debuted way back at the Los Angeles Olympics. I wonder why Nikon did not resort to such a solution for its new 800mm f/5.6 lens, since the size of the dedicated 1.25x converter is truly diminutive in comparison to the lens body anyway. Back to the Canon 200-400mm, that has got to be one of the most expected pro lenses from Canon in ages, Joshua finds it to be very sharp wide open, 'at least as sharp as the EF 300mm f2.8 L IS lens, or even the EF 400mm f2.8 L IS lens.

The lens is a pre-production model, and it is mounted on a 1DX body, but at these huge lens sizes its rather the other way around. Kudos to Canon if that will be proven in a more controlled testing environment. Furthermore, we get to see the 1.4x converter in action, and Joshua finishes the review by assuring us that a 2.0x tele converter CAN be used with this lens, with only a minimal sacrifice in image quality, producing a 1120mm f8.0 max tele range!  . . . read more

Canon EF 200-400mm f/4 L IS USM Extender 1.4x Lens Review @ The Digital Picture

"The Canon EF 200-400mm f/4 L IS USM Ext 1.4x Lens has inherited the built-in 1.4x extender (in concept at least) from the rare Canon FD 1200mm f/5.6 L Lens (picture on PBase.com). The 200-400 L is the first EF lens to receive built-in, switch on/off extender. 

I love the concept. A lockable lever is used to move lens elements into or out of the optical path. A unique bulge is present near the lens
