Trio Video Chooses Canon Lenses For Mobile Unit
Trio Video, a mobile production company, provides facilities and crews nationwide for broadcast and cable clients, entertainment companies, professional sports teams, and major corporations. Among the mobile units that Trio Video operates is Tempo, a 48-ft. trailer (with a 29-ft. expandable side) outfitted with advanced HD equipment selected to provide picture quality and reliable operation that meet the demands of HDTV location production. Included in this equipment array are six long-zoom HD field lenses and five portable HD zoom lenses, all of which are from Canon U.S.A.
Canon lenses mounted on Tempo’s HD cameras include two XJ86x9.3B and four XJ75x9.3B long-zoom HD field lenses, three HJ22ex7.6B long-zoom portable HD lenses, and two HJ14ex4.3B wide-angle portable HD zoom lenses.
Equipped with Canon’s built-in Optical Image Stabilizer, or “Shift-IS” system, the XJ86 and XJ75 long-zoom HD field lenses are designed to provide cameras with clear images even at telephoto distances. The XJ86 is available in three versions, including Auto Focus and extended telephoto. The XJ75 long-zoom HD field lens is designed to cover various sports and entertainment events, and combines optical, mechanical, and digital technologies with modest size and weight.
Both the XJ86 and XJ75 long-zoom HD lenses are part of Canon’s DIGISUPER line of high-performance field and studio lenses. All feature a computer-aided lightweight design, multilayer coatings on each optical element, and Canon’s second-generation digital servo systems for improved ease-of-operation as well as tactile control of zoom, iris, and focus; precision repeatability of settings; and microcomputer compensation of lens-focus breathing (the inadvertent alteration of field-of-view when operating the focus control).
Portable HD lenses chosen by Trio Video consist of two of the newest products in Canon’s HDxs line. The HJ22ex7.6B is the longest-focal-length portable HD production lens offered by Canon (without an image-stabilization system). Offering a range of creative options, the HJ22 portable HD lens is designed for long-distance shooting combined with wide-angle capture in a lightweight (4 lbs.) form factor. The HJ14ex4.3B portable HD zoom lens combines a 14 times zoom range with a minimum focal length of 4.3 mm and an angular field of view of 96.3 degrees at the wide end of the 16:9 HD aspect ratio. The 14x zoom range of this lens reaches to 60 mm (120 mm with extender).
Both the HJ22 and HJ14 portable HD zoom lenses also feature Canon’s Digital Drive unit built into the hand grip, enabling camera operators to pre-program settings for iris, focus, and zoom positions and speed, if desired. The Canon-developed rotary encoders inside the Digital Drive units can also output this positional lens data via a connector so it can be used with virtual studio systems.
