Gossen Luna-Star F2, Digital Incident, Reflected, Ambient and Flash Light Meter


About Gossen

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.

from San Diego, CA

The nicest meter I've used!! It takes one standard 9V battery that you can buy anywhere. It only has six buttons and their functions are obvious. I was able to use all but one of the meter's modes within 60 seconds of putting in the battery without reading the manual. 99% of what you'd need to know from the manual is printed in four sections on the back of the meter. The meter is great for computing lighting ratios. You press the measurement button once to take a snapshot reading. You press and hold it while sweeping the meter around a scene and the Luna-Star F2 draws you a graph at the bottom of the display of the contrast range (e.g., f8-f16). Every time you take a flash reading, the meter also shows you the ambient reading with an unobtrusive little bar on the same graph. Unlike the Minolta meters, you don't need a "reflected attachment" and an "incident attachment." The naked meter works to measure reflected light. Add a plastic incident piece and you can measure incident light. Add a little viewfinder and you've got a 5 degree spot meter. It is a great design and smaller than competing products. The ONLY reason it did not get a 5-star rating is because it only meters down to EV -2.5. That's a couple of stops less light than most pro SLRs but not as good as some other handheld meters.
