Sony HVL-F28RMA Overview
Equipped with a 2.4 GHz radio transceiver, the HVL-F28RM can operate as either a radio commander or remote as part of Sony's radio wireless system, including the FA-WRC1M Wireless Radio Commander and FA-WRR1 Wireless Radio Receiver. This system has an operating range of approximately 115' and does not require line-of-sight. It supports up to 15 flashes in five groups on one of 14 channels and offers full support for Sony's P-TTL / ADI metering system, including high-speed sync and ratio control.
Advance Distance Integration (ADI) flash metering works with cameras and lenses with distance encoders to more accurately balance flash output with ambient light and subject reflectivity by taking camera-to-subject distance into account.
Guide number of 92' at ISO 100 and 50mm.
Flash head offers 0 to 120° tilt for bounce control.
Covers a 50mm focal length field of view with a pull-out wide panel to broaden this coverage to a 24mm focal length field of view.
Manual power adjustment is possible across 25 levels, covering full 1/1 power down to 1/256 power.
Fires continuously for up to 40 flashes at a rate of 10 flashes per second.
Slow, high-speed, and 1st and 2nd curtain sync is supported on cameras with TTL communication.
Recycle time of 0.1 to 6.4 seconds with alkaline batteries or 0.1 to 4.1 with NiMH batteries.
Improved resistance to overheating for longer and more rapid shooting sessions.
Dust- and moisture-resistant construction enables its use in harsh environments, and a durable metal shoe has been added for improved mounting stability.
Requires two AA-sized batteries, either alkaline or NiMH, as a power source.
Micro-USB port can be used for firmware updates.
