#4200 Digital Exposure Meter provides accurate readings for both ambient light and flash photography. This is a completely new compact amphibious design for use above water or 200 feet underwater. Two sensors provide maximum capability. One sensor monitors a water contact incident light sphere; or choose the direct reading sensor on the opposite side that covers about ten degrees. The size is comparable to digital meters intended for use only above water. It is 1.375" thick, less than 3" wide, and less than 5" high including the mounting and lanyard loops. Bracket is included for attachment to most Ikelite handles. The meter automatically shuts down after about five minutes if not in use, or can be locked on for continuous operation. Memory feature retains all settings (ISO film speed, exposure compensation, etc.) when the meter is turned off or the battery is changed. |
