Olympus PEN-F Flash


The PEN-F comes bundled with the Olympus FL-LM3 compact flash unit which is capable of bounce/swivel. It features a Guide Number (GN) of 9 meters at ISO 100 and derives its power from the camera body.


Bundled Flash Test Results

Range
A slightly dim exposure at the specified range.

We didn't test flash coverage or exposure of our Indoor Portrait scene since that is lens dependent and the PEN-F does not ship with a kit lens. We did however check Olympus' flash range claim for the bundled flash below.

Manufacturer-Specified Flash Range

7.5 feet,
f/5.6, ISO 200

Manufacturer Specified Flash Test. The Olympus FL-LM3 bundled flash has a Guide Number (GN) of 9 meters at ISO 100. That works out to about 7.5 feet at f/5.6 and ISO 200. In the shot above, the FL-LM3 did not quite perform to Olympus' GN spec in terms of range, producing a somewhat dim exposure (about 0.5 EV underexposed) at the calculated distance, aperture and ISO. You can of course use a more powerful flash unit if you find the bundled unit is not powerful enough for your needs.
