· Type : Digital light meter for ambient and flash light

· Light receiving method : Incident light and reflected light

· Light Receptors

Incident light : Convertible to flat diffuser (Lumisphere in down position)

Reflected light : light receiving angle 54° (lumigrid)

· Light receptor element : 2-Silicon photo diodes (incident and reflected)

· Metering modes

Ambient light : Aperture priority metering

Shutter priority metering

EV metering

Flash : With synchro cord (cumulative, non-cumulative)

Without synchro cord (cumulative, non-cumulative)

Measurement using the optional wireless flash radio triggering sys-

tem (cumulative,non-cumulative)

· Measuring Range (ISO 100) :

Ambient light : Incident light EV-2 to EV 22.9

Reflected light EV-2 to EV 22.9 (with 54˚lumigrid)

Flash : Incident light f1.0 to f90.9 (approx. F124)

Reflected light f1.0 to f90.9 (approx. F124) (with 54˚lumigrid)

· Repeat Accuracy : +/- 0.1 EV or less

· Calibration Constant :

Incident light metering : Lumisphere C = 340 Flat diffuser C = 250

Reflected light metering : K = 12.5

· Display Range :

Film speed : ISO 3 to 8000 (in 1/3 steps)
