The Sony HVL-F60RM lets you take many photos one after the other, thanks to the charging time of 0.1 to 1.7 seconds. This makes it suitable for professional photographers. The flash has a guide number of 60 and lets you light objects nearby and far away. The automatic zoom range of the flash is 20 to 200 millimeters. This means that the flash zooms as your lens does. Sony's Quick Shift Bounce system lets you easily tilt the flash from horizontal to vertical. That's useful when making portraits, for instance. In order to determine the intensity of the flash, the flash makes a test flash with the TTL function. You can control up to 15 flashes and 5 groups with the optical and wireless radio controls.
