Lens specifications: Optical 18 × , f = 4.1 to 73.8 mm (F1.4 to F3.0) The horizontal angle of view is approximately 48 degrees (wide end) to 2.7 degrees (tele end). Digital Zoom enlarges the[...]

8 Basic Functions To avoid AF error from continuous 24 hour AF mode usage, daily initialization of lens system using the CAM_Initialize command is recommended. The CAM_Initialize command takes less than 3 seconds to initialize the focus and zoom. • Manual Focus Mode MF (Manual Focus) has both a Standard Speed Mode and a Variable Speed Mode. Stand[...]

9 Basic Functions AE – Shutter Priority The shutter speed can be set freely by the user to a total of 22 steps – 16 high speeds and 6 low speeds. When the slow shutter is set, the speed can be 1 / 30 , 1 / 15 , 1 / 8 , or 1 / 4 s. The picture output is read at a normal rate from the memory. The memory is updated at a low rate from the CCD. AF c[...]

10 Basic Functions When switching from the Shutter Priority mode to the Bright mode, the shutter speed set in the Shutter Priority mode is maintained. Spot Exposure Mode In Full Auto AE, the level for the entire screen is computed and the optimum Auto Iris and Gain levels are determined.
