Digital Quick Zoom Quick Zoom speed is improved to 0.7 seconds end to end. Quick Zoom provides for a rapid zoom movement to the telephoto position to check focus with the simple push of a button. Releasing the button returns the lens to the previously selected zoom position. Quick Zoom can now be performed remotely from the ERD-T22 and ERD-10A-D01 No other lenses come close in performance or features |

Vformat All new Fujinon lenses are compatible with the currently proposed 16:9 format. However, because of the various methods of achieving the 16:9 ratio, it is important to understand how the methods of ratio conversion are achieved. There are two types of switchable-format cameras available today. One type uses 16:9-format CCDs and switches to the 4:3 aspect ratio. The other utilizes 4:3 CCDs and switches to the 16:9 format.When the 16:9-format CCD system is employed, it is necessary to compensate for a loss in angle of view of about 20 percent that is incurred when switching to the 4:3 aspect ratio. To eliminate this problem, Fujinon offers an optional ratio converter that is located in a four-position extender turret in studio and field lenses, and in an enlarged extender housing in new hand-held lenses. An additional option for lenses with an 82 mm filter thread (A18X7.6) is the lightweight front-mounted converter model RCV-82SC. |
