Leica RC30 Aerial Camera System

Product Description

Overview

The Leica RC30 is an aerial film camera system oftop quality and performance, capable of acquiringthe very best aerial photographs with black andwhite, color and false color aerial film. There aretwo lens options, with 6-inch and 12-inch focallengths. Forward motion compensation, automaticexposure control and film data recording areprovided as a standard feature. A comprehensiverange of accessories includes filters, navigationsights and video intervalomers. The camera is partof an overall system, which may comprise of theLeica PAV30 gyro-stabilized mount, the LeicaASCOT Aerial Survey Control Tool, a GPS referencestation, a GPS/IMU position and orientationsystem, and an optical window for pressurizedaircraft.
