The Gossen Digiflash Light Meter 2 is ideal for photographers who seek optimal performance in a minimal form factor. This meter utilizes incident light measurement with integrated contrast measurement to indicate whether or not subject contrast - the difference between the brightest and darkest part of the subject, can be managed by the sensor or the film. As its name implies, the Digiflash Light Meter 2 also reads flash. The LCD screen reads out in both ISO and EV values.
