The Sony HVL-F58AM Flash Unit delivers flexible lighting control for α (alpha) DSLR photographers. The innovative new “Quick Shift Bounce” system allows the flash to pivot 90 degrees left and right to maintain a proper lighting position, even when shooting vertically. The HVL-F58AM can also wirelessly control up to three groups of flashes, and Wireless Ratio Control allows users to specify luminosity ratios for each group. Additionally, the HVL-F58AM features an effective range of more than 45 feet (14.5m) and a fast, 5 second recharge time. A built-in wide panel and bounce sheet provide an even greater degree of creative control.
