The Canon HJ40 is a superb example of an HD telephoto lens that captures fantastic panoramic images over a long distance.

Perfect for sport and entertainment

The HJ40 is perfectly designed for sports, live events and broadcast. It has an impressively wide focal range of 10-400mm. And a built-in 2x extender doubles its capability to 800mm.

Comfortable in all shooting scenarios

With a weight of 5.5kg, the HJ40x10B IASD-V HD lens is equally comfortable in an array of remote shooting situations. It is equally at home in applications such as aerial photography, fixed positions in sports stadiums and events venues, or in more portable shoots in rough terrain.

Compatible with all our B4-mount cameras, the Canon HJ40 is a true stalwart of OB and ENG shooting. It is sturdy, reliable and highly flexible, with no compromise on image quality.
