Though compact and lightweight, the HVL-F20AM has a maximum range twice that of the built-in flash units on á230, á330 and á380 cameras. This is represented as the guide number (GN) of 20 with a 50mm focal distance at ISO 100.
When set to ‘indoor’ shooting mode, the flash points up to bounce light off the ceiling for shadowless illumination of your subject. When set to the ‘outdoor’ shooting mode, the flash directs light directly at your subject.
With the built-in diffuser the flash illumination covers an angle of view of 27mm at the default Standard Position setting. If users want to to shoot at a greater distance, they can rotate the dial on the side of the flash unit to the ‘Tele’ Position*. Although this reduces flash coverage to an angle of view of 50mm, it extends the range to illuminate more distant subjects.
