The Bower SFD728 Autofocus TTL Flash is a dedicated shoe-mount flash with E-TTL / E-TTL II exposure metering capabilities for Canon cameras. The flash features a guide number of 92' at ISO 100 and a TTL range of 45.9' for automatic control of the flash output. The four-position zoom head covers a focal length range between 28mm and 85mm and a 0-90° bounce and 330° swivel design enables extensive head positioning capabilities.

An infrared AF assist beam is integrated into the flash's design to promote faster focusing in low-light conditions and an intelligent auto-check light is also available to confirm if the subject is within TTL range. Red-eye reduction and second/rear-curtain sync modes are also available when used with supported cameras.
