LUNA-PRO S /  Cat. No: GO 4020   => Old Cat. No: 4020
Ambient Lightmeter; CdS Sensor, Null Metering, w/Case, Strap and Batteries, System Accessories Available.

Exposure measuring in the light of the sun and the light of the moon.

The symbols of the Sun and the Moon in the middle of the calculator disc represents the two measuring ranges which can be selected in the Luna-PRO s with the tumbler switch.

At dusk, the time between day and night, the Luna-PRO s performs at its very best. Its low end range value being -4 EV, the meter has ample capacity for extreme low light levels with very long exposures. It is especially useful that the indicator needle stays locked, once the reading has been made. Transfer the number indicated by the needle to the corresponding number on the yellow scale, against the yellow index mark and you can read off the required shutter speed, f/stop combination of the calculator dial, it’s so easy
.

    Technical Highlights:

  • Incident and reflected readings in ambient light.
  • Extra large measuring range, divided into high light and low light scales.
  • Scales for shutter speeds , F/stops, exposure values, cine speeds, and the zone system.
  • Setting ring for exposure corrections and extension factors (with a highly visible red reminder indicator).
  • Five useful attachments for further expanding the capabilities.
