Sony HVL-F45RM Wireless Radio Flash for Sony Multi Interface Hotshoe

Equipped with a built-in 2.4 GHz radio transceiver, the HVL-F45RM Wireless Radio Flash from Sony will help users quickly create portable lighting setups with complete support for P-TTL / ADI metering. This flash can be set as a commander or a remote that fully supports Sony's existing radio commanders and receivers, including ratio control, the ability to work with up to 15 flashes in five groups, and access to 14 channels. The flash works within Sony's optical wireless flash system as well, where it is also able to operate as either a commander or remote unit.

Improving upon the previous model, the HVL-F45RM reduces size and weight by over 10% while improving the guide number to 148' at ISO 100 and 105mm and improving the recycle time to 2.5 seconds. Full bounce capabilities are available as well with tilt from -8 to 150° and a total of 360° of rotation. Also, it has a zoom head of 24-105mm which can be expanded to 15mm with a pull-out diffusion panel alongside an LED light useful for video. The flash offers vastly improved controls via the rear LCD, including customizable buttons and flash distribution and memory settings. Additionally, the flash has a dust- and moisture-resistant construction.
