The HVL-F43M TTL Shoe Mount Flash is an auto / manual flash unit that offers flexible lighting control and is compatible with Sony's Multi Interface shoe. Its Quick Shift Bounce system allows it to pivot 90‹ left and right, allowing you to maintain horizontal light distribution even when shooting vertically. Additionally, this external flash features an effective range of more than 30 feet (10.5m) while a built-in wide panel and bounce sheet provide an even greater degree of creative control.
