Overview
The EF 400mm f/2.8 L IS II USM is designed as the perfect companion for a professional wildlife & nature photographer. Light, sharp and with a wide maximum aperture of f/2.8 this lens is every bit a professional as the person wielding it. Designed for professionals this is by far the most expensive and most well built 400mm prime that Canon currently sells. At $11,500 it is certainly a lens that will burn a hole in most pockets.
Canon has used fluorite optical elements in the lens ensuring much less effect from color fringing (lateral chromatic aberration). An additional fluorine coating ensures that the lens can prevent against finger prints and dust smears. The Image Stabilization (IS) technology has been revamped giving the lens up to four stops of stabilization for hand held shots. A new third IS mode (IS3) in the lens activates IS only when the shutter button is fully pressed. It also detects when the camera is doing a panning shot and disengages IS.
The lens has inner focusing system which evidently means that the barrel length does not change during focusing. The lens construction is extremely good with weather (both water and dust) sealing making it suitable for rough use out in the open. Professionals shooting in demanding conditions and looking for an all weather lens would love this light and weather sealed f/2.8 400mm prime. The lens has a total of 16 elements arranged in 12 groups. The diagonal angle of view of the lens is 6° 10′. The external dimensions of the lens are 6.4” x 13.5” and the weight is 3850 grams.
