Measuring Modes -
Ambient : Aperture priority measuring, Shutter speed priority measuring, TF priority measuring, Cine measuring, HD Cine camera measuring, Illuminance measuring (lux, foot candle), Luminance measuring (foot-lambert, cdm2)
Flash : Cord Mode (with/without multiple cumulative), Cordless Mode (with/without multiple cumulative), Radio triggering Mode (with/without multiple cumulative)

Measuring Range -
Ambient- Incident : EV -2 to 22.9 (approx. f/2 at 15 sec. to f/22.9 at 1/8000 sec.) / Reflected: EV 3 to 19.9
Flash light- Incident : f/1.0 to f/128.9 / Reflected: f/2.8 to f/128.9
Illuminance- 0.63 to 2,000,000 lux / 0.10 to 180,000 fc (EV -2 to 19.6)
