Canon CJ14ex4.3B IASE S 4K Lens

The portable CJ14ex4.3B IASE S is an important 4K UHD telephoto zoom lens that is part of our 2/3-inch UHDgc series. Its compact size and low weight support the high mobility shooting often entailed in documentary and many other genres of television field production.  This lens enhances current HDTV optical imaging performance while potentially future-proofing anticipated 4K production.  This lens enhances current HDTV optical imaging performance while potentially future-proofing anticipated 4K production. This lens enhances current HDTV optical imaging performance while potentially future-proofing for anticipated 4K production needs. The 14x zoom ratio supports a focal length range of 4.3 - 60mm (and 8.6 - 120mm with the built-in 2x extender). 4K resolution is maintained over this total focal range and across the 16:9 image plane. Design strategies have extended the optical dynamic range to meet contemporary HDR imaging requirements. The lens also supports the wider color gamut specified in the international standard ITU-R BT.2020. An advanced digital drive unit deploying 16-bit encoders is fully compatible with the zoom, focus and iris controllers used with established broadcast 2/3-inch HDTV cameras. Three 20-pin connectors on the drive unit interface with these controllers (such as ZSC-300D and FPD-400D) while also providing a 16-bit interface to virtual systems.
