Canon’s 4K cinema servo lens
By David Fox
CANON’S NEW CN7x17 KA S is its fi rst cinema lens to feature a servo drive unit, making it more suitable for handheld broadcast use for 4K and large sensor cameras. It is claimed to offer a best-in- class focal length of 17-120mm, and is available in EF-mount and PL-mount versions, while the addition of the servo drive unit, with high speed zoom, iris and
IDX Cue battery cost savings By David Fox
THE NEW Endura Cue battery range from IDX is claimed to combine enhanced reliability with lower cost. The Lithium Ion batteries have been designed to meet the most stringent PSE regulations for electrical and mechanical safety — essential for air travel. There are three V-Mount models:
Endura Cue-D75, Endura Cue-D95 and Endura
Cue-D150. All have D-Tap DC output, allowing peripherals to be powered direct, while a discharge cut off prevents them being damaged by products without a voltage-sensing shut down mechanism. Four LEDs provide a quick check of remaining power capacity. The range comes with a one-year
capacity better than 70 per cent and a
two-year defects warranty.
The cells have been supplied by Sanyo, which has combined improvements in design and manufacturing with developments in microchip technology to reduce the
component count and improve reliability. The Cue range includes battery circuit protection to counter overcharging or exposure to high temperatures. 11.C21
Right on Cue: the new Endura Cue range from IDX
BONDED 3G/4G uplink technology used during coverage of both the FIFA World Cup in Brazil and the Sochi Winter Olympics will be on show at the LiveU stand. The range of portable live video acquisition, contribution and management innovations includes the LU500 and the DataBridge. The former, which weighs 1kg (2.2lbs) and is available in both backpack and camera-mount versions, is based on patented bonding algorithms and is powered by a new multi-processor video encoding engine.
The LiveU DataBridge is a mobile hotspot that offers broadband connectivity in any location by bonding together multiple cellular and other data connections.
Also being demonstrated during IBC will be a browser- based management system for controlling and tracking LiveU systems, feeds and apps. LiveU Central enables a live preview of all incoming feeds to be dragged and dropped onto a physical server output anywhere around the world or be encoded for web streaming. LiveU’s mobile application for smartphones and tablets, the LU-Smart will also be on show, along with the Xtender external antenna for extra-resilient signal in extreme scenarios. 3.B62
focusing, lends itself to a more fl uid shooting style, for drama, documentaries or current affairs. Its low speed drive functionality offers greater control over slow zooming, while immediate start- up means shots won’t be missed in dynamic situations. It supports 4K resolution shooting, with a 7x zoom range and a maximum T-number of T2.95.
The lens is also suited to tripod-mounted use. Zoom,
focus and iris can all be controlled using Canon’s existing zoom and focus demands. Virtual studio use is also supported via 16-bit encoder output.
For more traditional movie- style shooting, the servo drive unit can be removed completely, with follow focus units and matte boxes fi tted, while re-installation is quick and simple, with no adjustment of gear positions required.
The CN7x17
KAS S supports communication between lens and camera. The EF-mount version uses Canon’s own system, while the PL-mount variant is the fi rst in the Cinema EOS series to support Cooke’s /i Technology. There is also support for 12-pin serial communication. Canon will also be showing more than 100 lenses in a vast array of focal lengths and types,
from ENG to cinema to EF
lenses, at IBC, as well as numerous 4K demonstrations, including 4K output from studio camera confi gurations and live colour grading enabled by its 4K reference monitors. 11.E50
