This cable requires a separately available Promote Control HDR bracketing controller unit.
Using this cable enables the following modes of operation with select Sony Alpha cameras:
Other Promote Control modes are not compatible with Sony Alpha cameras at the moment. Regular USB-based HDR bracketing mode is not compatible with Sony Alpha cameras. As a result, HDR bracketing mode is limited to the shortest exposure of 1/20 to 1/5, depending on your camera model. Please see Bulb HDR section in Promote Control User Manual for more information.
IMPORTANT: This shutter cable also requires a Bulb Ramping / Bulb HDR Assist Kit to be connected. It is thus ONLY compatible with Sony Alpha cameras that also have a PC Flash socket or a standard flash hot shoe. Examples of supported Sony Alpha cameras are:
Other Sony Alpha cameras may also be compatible if they have a round PC flash sync socket, or a standard hot shoe (see above links for more information).
IMPORTANT: Sony cameras with a proprietary Sony hot shoe are also supported via an optional third-party adapter that provides a round PC flash sync socket. Other similar adapters may also work.
