Canon announces new 4K broadcast lens alongside EOS C70 camera

Lens and camera are aimed at broadcasters, documentary makers and news operations

Canon has added to its range of 4K broadcast lenses with the launch of the CJ20ex5B.

The 2-in-1 UHDxs-class lens has a 20x zoom range and 5mm wide-angle – making it suitable for a wide range of broadcast applications such as studio filming, sports production, documentary shooting and news gathering.

The CJ20ex5B is equipped with a 16-bit absolute value encoder that can read out highly accurate positional information of each lens settings – zoom focus and iris without initialising the lens. According to Canon, its 3 x 20pin connectors enables the lens to read out such information even when using the zoom and focus controllers at the same time.

The CJ20ex5B’s key features include:

  • UHDxs class 4K optical quality
  • Hybrid Concept wide & telephoto
  • 5.0-100mm focal length (10 -200mm with optical extender)

The camera has launched alongside the Mount Adapter EF-EOS R 0.71x  – an EF Lens to RF Mount which enables filmmakers to use the entire EF lens line-up with the EOS C70.
