The Canon HJ21ex7.5B ITS-RE is a high quality 21x zoom lens for professional 2/3" remote video cameras. This model is highly versatile and can be used in a variety of professional applications, including teleconferencing, distance learning, and specialized broadcasting including sports coverage. The focal-length range is 7.5-158mm with a minimum object distance of 2.8' (0.9 m) and features a 2x extender for increased telephoto capability. Additionally, the lens comes equipped with a motorized operated 2x extender which can be coupled with an external control unit.
Video Conferencing Remote Control
Designed to fit a remotely controlled and monitored pan and tilt system, this lens is particularly suited for the highest quality industrial cameras, as well as high definition broadcast including sports coverage.
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.
Integrated 2x Extender
For instant close-up images 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.
Internal Focus for Ultimate Versatility
The lens is made for the highest quality professional video cameras. The front lens element is stationary and can be used with a matte box for greater lens flair protection as well as a wide array of square and rectangular filters.
