Along with the Canon EOS C300 Mark III camera and the Canon CN10X25 IAS S universal servo lens, Canon introduced the CJ18ex7.6B KASE, a compact and lightweight broadcast 4K lens for cameras with a 2/3 inch optical format sensor with B4 mount.

This lens covers a range of focal lengths of 7.6–137 mm, that is, it offers an 18x zoom. In the area of ​​7.6-103 mm, the maximum aperture is f / 1.8, in the 137 mm position – f / 2.4. According to the manufacturer, thanks to the innovative design without an extender, the lens turned out to be much lighter and smaller than its predecessors. At the same time, it provides “impeccable 4K resolution from the centre to the very edges of the screen.”

To reduce chromatic aberrations, elements of fluorite and glass with ultra-low dispersion are introduced into the optical circuit, and a special coating reduces the risk of glare and spurious reflections. The lens dimensions are 160.5 x 105.0 x 206.2 mm, and the mass is 1.4 kg. Due to its compactness and lightweight, the CJ18ex7.6B KASE is well suited for continuous shooting from the shoulder and does not limit freedom of movement.

The CJ18ex7.6B KASE has three 20-pin connectors for integration with various virtual studios, including all-wheel-drive systems. Using a 16-bit converter to read the lens settings simplifies calibration when combining real and virtual images.

Sales of CJ18ex7.6B KASE will begin in June.
