Canon EF 400mm f/4 DO IS USM

Handholdable super telephoto lens, awesome results.

As denoted by its green stripe, the EF 400mm f/4 DO IS USM utilises Diffractive Optics, making it relatively small and lightweight for a super telephoto lens. However, just because it’s small, doesn’t mean it can’t offer big results. Thanks to its relatively small stature, you can enjoy comfortable handholdability – a feature that is accentuated by Canon’s exceptional Image Stabilisation technology. On this lens, there are two modes of IS available: Mode 1 attempts to stop camera and lens motion in all directions when capturing stills, while Mode 2 stabilises camera motion on one axis, allowing for stable panning. As for optical performance, the EF 400mm f/4 DO IS USM delivers impressive results, allowing you to create images that are remarkably sharp. This is helped in part by its ring-type USM autofocus, which is fast, accurate and quiet. All this and more make this an excellent sports photography lens, wildlife lens and general super telephoto.p>
