Overview

Our 2/3- inch format studio lens with RBF

The UHD-DIGISUPER 27 RBF  (UJ27×6.5B) studio lens is our 2/3-inch format studio lens, featuring outstanding optical performance beyond 4K resolution with a 27x zoom ratio (6.5mm to 180mm) and wide angle focal length (6.5mm at 1×, 13mm at 2×). A variety of Canon’s advanced optical design technologies combine to produce a lens that delivers both 4K resolution and color reproduction uniformly from the center of the screen to the corners.

The UHD-DIGISUPER 27 RBF also facilitates remote back focus (RBF) with select Sony cameras1 from a control room, TV truck or OB Van.  RBF control is achieved by virtue of a motorized rear flange back built into the lens. Control of the flange back is achieved from a compatible Sony Remote Control Panel (RCP)2. As a result, a video engineer working in a remote control room or TV truck can adjust critical back focus. This can come in handy if the camera operator has to step away or the back focus adjustment needs to be re-adjusted due to environmental conditions. 

Optical Performance that Exceeds 4K Resolution

The most advanced computer simulation design techniques, deployment of new glass materials and optical coatings, and new precision optomechanical design strategies form the underpinnings of the outstanding overall optical performance of the UHD-DIGISUPER 27 RBF (UJ27x6.5B) – achieving beyond 4K resolution even when the built-in 2x extender is engaged. These proprietary design strategies deliver exceptional 4K image sharpness and a very high contrast across the entire image plane and across the visible wavelength spectrum.

Ideal for HDR Image Capture

Recognizing the new importance of High Dynamic Range (HDR) to enhancing the overall image performance of both UHD and HD, the lens has been designed with proprietary coating and anti-reflection materials to precisely manage internal light reflections and to better suppress unintended ghosting and flare. This helps produce superb contrast and color reproduction of nominally exposed images, enhanced reproduction of scene speculars, and tight control over spurious effects of extreme scene highlights.

Stable Servo Performance

A 2/3-inch 4K acquisition system can result in a narrower depth-of-field than an equivalent HD system, making achievement of accurate focus more critical. To help alleviate this challenge, the operation of the focusing system within the lens has been improved compared to previous models, which aids operational tracking of focus on selected scene objects even when fast zooming is also engaged.

Compatible with Existing Lens Controllers

The lens utilizes the same standard controllers for zoom and focus operations that have been optimized over decades of Canon HDTV field lens developments. Similar in size and weight to our 2/3” HD lenses, the UHD-DIGISUPER 27 RBF allows for the same shooting style.

16 bit Output to Support Various Virtual Systems

The lens is equipped with 16-bit optical rotary encoders to output highly precise positional data of zoom, focus and iris on a 20-pin connector for direct digital interface to robotic and virtual studio systems.
