Godox RS-600P & RS-400P Wireless Strobe
The RS-400P (400W) and RS-600P (600W) are Godox's earlier 433Mhz wireless strobes designed for use with the FT-16 wireless hotshoe transmitter. As far as functionality goes compared to their latest HSS / TTL offerings like the AD600 / AD360ii the RS line of portable strobes are on the light side.
Still retaining prior 433Mhz remote transmitters and receivers that offer less line of sight distance and reliability compared to later 2.4Ghz models. The RS-400 does offer 650 Full power flashes per charge being that the battery pack for these strobe is not an all in one package, weighing in at 3kg for the battery alone. There is no HSS or TTL so shutter speeds must remain for the A7r below 1/160th and 1/250th for the A7 - both of which can be pushed a further stop with minor banding fixed in post.
The RS-400P retails around $530 AUD
The RS-600P retails around $640 AUD
