Powerful Zoom Range (21x): Focal length range of 7.5mm – 158mm (without extender), covering wide-angle to medium telephoto.
HD Optical Quality: Advanced optical design utilizes aspherical and low-dispersion elements to ensure sharp images, high contrast, and minimize chromatic aberration across the entire zoom range.
Optical Stabilization System (Shuttle Shot): Ensures smooth, high-speed, and reliable zoom movements. Integrated 2X Extender: The built-in 2x optical extender increases the focal range up to 316mm, useful for distant shots.
Digital Control Support: Digital servo control system allows for precise zoom and focus control, as well as remote operation capabilities.
2/3 inch Mount: Compatible with all 2/3 inch HD/UHD Broadcast cameras (such as Sony, Panasonic, and cameras using the B4 mount).
The HJ21x7.5B lens is optimized to meet the high resolution of 2/3 inch HD cameras. It delivers sharp images even at the widest (fastest) aperture and maintains high resolution from the center to the edges.
Minimized Breathing Effect: The optical design minimizes focus breathing, which is crucial in live zoom/focus situations.
2. Advanced Digital Control:
Canon’s digital servo control system offers the ability to store and recall precise zoom and focus settings (Zoom/Focus Preset), allowing the operator to execute complex maneuvers repeatedly and accurately.
Auto Focus/Manual Focus Function: The control lever allows for quick switching between autofocus and manual focus.
3. Durability and Reliability:
Sturdy, durable mechanical design built to withstand the harsh environments of news and sports production. Meets Canon’s high quality standards for Broadcast equipment.
4. Fast Aperture:
The maximum aperture of f/1.8 at the wide end (7.5mm) and f/2.8 at the telephoto end helps the lens perform well in low-light conditions.
