Canon has introduced new professional zoom lens for the broadcast market: The Canon 10x16 KAS S zoom lens offers 8K resolution for modern 2/3″ broadcast cameras. This is the third lens in Canon’s broadcast series that covers 1.25-inch sensors.
   

This new lens is being marketed by Canon as a complement to the existing high-performance UHD-DIGISUPER 51 box lens (15.5 – 790 mm) and the handheld 7x10.7 KAS S zoom lens (10.7 – 75 mm), both of which are capable of delivering 8K resolution to the 2/3″ sensor.

It offers a fast aperture of f/2.8 over the entire zoom range and is equipped with an 11-blade diaphragm. The closest focusing distance is specified at 0.9 m (from the front element).

The lens itself measures 247 mm in length, while the front diameter is 114 mm. The whole thing weighs about 2.94 kg.

What is missing from this lens is an internal extender, which is quite common in broadcast lenses. Normally, there is a 1.5x internal extender that can be engaged by flipping a mechanical switch.

What we do get are the usual interfaces to external devices, such as remote zoom grips or follow focus units. The handle has motors for all three mechanical sprockets in it, so you can operate them remotely or from behind a tripod in larger studio setups where it’s a bit inconvenient to reach for the lens. The lens must be connected to the host camera to receive power for the motors.
