The Canon HJ40x10B IASD-V is a portable EFP lens designed for documentary, natural history, and wildlife shooters that need to capture sharp, crisp images from a great distance. Its superb built-in image stabilization also makes it ideal for aerial, concert, and sporting events that require both longer zoom ranges and portability. Shuttle Shot, an enhanced servo system, lets the operator zoom back and forth between two positions for either checking focus or precise zooming, while the design incorporates a dual lens approach to broaden the shooting options, achievement of an adequate sensitivity, maximization of image contrast, and preservation of the highest MTF over the long focal ranges.
