The Profoto A1 AirTTL-C Flash produces a soft, natural light on the subject of photography. It can be mounted on your Canon DSLR camera. Its minimum recycling time is 1.2 seconds, which is four times faster than any ordinary on-camera flash. An LED modeling light is integrated into the flash to let you know how the lighting effect will turn out in the final output. A built-in air remote allows you to trigger the flash from a distance. The AF-assist beam makes the flash configure itself with the camera's autofocus settings. You may view the flash settings on the high-resolution display of the flash. The Profoto A1 AirTTL-C Flash has a built in motor-zoom and a TTL/MAN switch, and runs on a rechargeable Li-ion battery.
