Fujinon's XA20x4.1BMA was the original lens that JVC offered with their GY-HM850U camera.
For superior low-light performance and assured brightness at the tele end, the lens offers F1.6-3.0, a focal range of 29mm — 580mm (35mm equivalent) and includes servo zoom, along with manual focus and iris rings. Optical image stabilizer and chromatic aberration correction are also built into this interchangeable 1/3-inch bayonet mount lens.
The built-in Optical Image Stabilizer (OIS) helps to correct lateral and vertical movement of the camera, ensuring that pristine HD images remain sharp and stable.
For studio rear control of this lens, use the HZ-HM600VZR Varizoom unit for focus, zoom and iris and VTR control. The HZ-ZS13U rear zoom control may also be used, but not the HZ-FM13U manual focus control.
