• Auto WB Adjustment
 The Auto WB adjusts the white balance automatically, with color temperature information signaled to the Alpha camera before WB is adjusted.

 
• High-Speed Sync
 The HVL-F42AM flash unit provides High-Speed Synchronization (HSS) mode that enables flash sync with shutter speeds from 1/500 to 1/4000 of a second to catch fast-moving subjects.

 
• ADI Flash Metering
 ADI (Advanced Distance Integration) metering capability enables the HVL-F42AM to work more effectively with lenses equipped with distance encoders, combining TTL (through-the-lens) flash metering with guide number control calculated automatically according to the distance to the subject, the ambient light and the pre-flash reflectivity of the subject.

 
• Can be triggered wirelessly (with TTL control) by the wireless operating mode available with Alpha series cameras.
