The most valuable feature is the rotating measuring head which is equipped with a diffuser dome for incident light measurement. The head will rotate through 270° which allows the photographer to see the large display while taking the readings.
Remove the incident diffuser dome and you can measure reflected light and subject contrast easily. The combined readout on the display is shown in both digital and analog form and provides a wealth of information.
Both flash and ambient light are measured at the same instant, so it's easy to determine the balance between flash and ambient light. Last but not least, the Luna-Star F2's outstanding ease of use with just six buttons covers all of the operations required. The ergonomic design allows easy one-handed use.
