Fujinon Offers New HD ENG Lens, Focus Assist System
February 28, 2005
Wayne, NJ - Fujinon is introducing its new HA25X11.5BERD HD ENG-Style lens for high definition applications.
Weighing 6.2 pounds, requiring no additional support, the new HA25X11.5 is a compact telephoto lens ideally suited for gyro stabilized platforms in aircraft, wildlife photography in remote areas and HD surveillance applications, where light weight and unobtrusive appearance are critical.
With a maximum focal length of 576 mm (2x), reduced focus breathing, an F-stop range of 2.0 to 2.8 and Fujinon’s exclusive DigiPower servo system for fast and accurate zooming, the HA25X11.5BERD is the perfect complement for remote-control system and location documentary work. It also provides widescreen 16:9 or traditional 4:3 production capability under the harshest of conditions.
Standard features on the HA25X11.5BERD include Fujinon’s Digi Power zoom and focus servo, 2x range extender, direct RS232 control and diagnostics. Optional features include: the TS-P41A optical stabilizer, servo controlled range extender, and the complete line of Fujinon remote control accessories.
The HA25X11.5BERD is designed to complement 2/3-inch high definition video cameras.
Fujinon is also introducing an expanded lineup of its patented, groundbreaking focus system designed to improve the quality of HDTV image capture in field and studio applications. The latest Fujinon Precision Focus Assist system, to be introduced at NAB2005, will be available on the company’s XA101x8.9BESM HD zoom, HA22X7.3BRD HD EFP lens and the HA13x4.5BRD-S28K HD wide-angle lens. Precision Focus Assist is a built-in feature that addresses precise focus issues in HDTV production stemming from the format’s shallow depth of focus and the lack of size and resolution in camera viewfinders.
This is not an auto focus system, but a focus assist that precisely adjusts the lens for optimum focus. Using this system, a selectable area of the video image is sampled as the focus point. The camera operator can adjust the user selectable point with a roller-ball type of controller, similar to a computer mouse, to position the focus point. The camera operator can then select manual or automatic focus assist. In the manual mode, there are three, colored LED’s that assist in achieving optimum focus. When the automatic mode is selected, the Precision Focus Assist system takes control and optimizes the focus, ensuring the captured image will be of the highest possible quality.
Additionally, when panning and tilting, the operator can follow the focus point and position it above the object of focus as the camera is moved with the controller. An added benefit of the Precision Focus Assist is that it does not require tight zooming to focus. It performs even on a wide shot.
Because the smaller viewfinders on HD cameras lack high-quality resolution, operators often believe they’ve achieved focus when they haven’t. And home viewers with 50” HD screens can easily see slight defocusing of the HDTV image that would not be discernable in standard definition. Remote controls were recently developed to allow video operators within view of a full-screen monitor to tweak the focus by referencing the large-screen monitor, but these systems have not been widely deployed. Fujinon brings the Precision Focus
Assist system to the market to address HD focus issues that weren’t answered with remote focus systems.
