The Canon J17ex7.7BWASE is a 17x wide angle 2/3" lens built to offer high performance in SDTV news gathering and field productions. Lightweight and durable, the lens weighs around 4 lbs and can be relied upon under harsh conditions. Additionally, the J17ex7.7BWASE is also equipped with features such as internal focus and shuttle-shot programmable positioning.
Shuttle-Shot Technology
The lens has added zoom capability; using the shuttle-shot switch. At the touch of a button, the lens can move to a pre-programmed point, going back and forth. This can be used both creatively, and as a no-hassle way of verifying focus.
Improved Image Quality
The lens element design greatly reduces aberrations and image distortions. These advances contribute to more balanced imaging from center to edge throughout the full aperture range.
Integral 2x Extender
For instant close-up shots, the lens has a switch that inserts an element that doubles the focal length at any point in the zoom range. Instead of using the zoom function, the extender gives immediate close-up images.
4:3 Crossover Technology
Achieving 4:3 aspect ratios from a 16:9 CCD is usually performed by cutting off the sides of the imager, effectively making the minimum focal length more telephoto. Canon's 4:3 crossover technology preserves the same picture angles by shortening the original focal length. Shots in standard 4:3 hold the same image size as if shot in 16:9.
