Fujinon XA55x9.5BESM-S5L 2/3" HD 55x Studio/Field Box Lens
The XA55x9.5BESM-S5L is a 2/3-inch box-style studio and field lens covering 9.5mm to 525mm at a 55x zoom ratio, extending to 9.5-732mm (19-1,464mm with the extender) for the shots that need every bit of reach a broadcast camera position can offer. Box lenses like this one live on a pedestal or a fixed platform rather than a shoulder, which is exactly where a lens this long belongs.
Maximum aperture runs f/1.7-2.9, bright enough to keep an image usable even at long glass, and the lens ships with its own lens support to carry the weight of the barrel off the camera mount. It is built for the high-zoom-ratio coverage that sports and large-venue productions need: a stadium sideline, an arena rig, or any position where the operator cannot walk the shot in.
