The Canon HJ40x14B IASD-V is a 40x super telephoto 2/3" lens built to offer high performance in HDTV applications. Best suited for documentary and nature videographey, the lens is highly durable and can be relied upon under harsh conditions. The unit is equipped with image stabilization technology along with features such as internal focus and shuttle-shot programmable positioning. The focal-length range is 14 to 560mm with a minimum object distance of 2.8 meters (9.2 feet) and comes with a 2x extender for increased telephoto capability.
High Definition Ready
Many high definition cameras are hamstrung by insufficient optics. Electronic Field Production (EFP) lenses traditionally have been built to accommodate standard definition. This lens is designed specifically with high definition in mind. The optics increase fidelity, making sure HD footage is crystal clear.
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 aperture range.
Built-In Image Stabilizer
Getting steady shots can be very difficult when shooting extreme telephoto images with relatively small cameras, often making footage unusable. With this problem in mind, Canon has incorporated a built-in optical stabilizer to help keep telephoto images silky smooth.
Shuttle-Shot Technology
The lens has added capability when zooming, 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 while providing a no hassle way of verifying focus.
Integral 2x Extender
For instant close-up shots, the lens has a switch which 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 System
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 by shortening the original focal length. Shots in standard 4:3 hold the same image angles as if shot in 16:9.
