All the information you need in a blink of the eye. If you're ever faced with changing light levels, backgrounds or unexpected movements, you know how important it is to quickly determine the correct exposure. Mamiya's PD Prism gives you the convenience you want and accuracy you demand by automatically coupling the aperture, shutter speed and film speed information. Advanced electronics eliminate the need for a separate shutter speed ring on the prism, and by using a system of color-coded LEDs in the viewfinder, exposure settings are easily made by adjusting the camera's shutter speed dial. FEATURES INCLUDE: Spot and Averaging TTL capabilities for versatility Sensitive, fast-reacting Silicon Photo Diode (SPD) sensor Bright, laterally-correct image
