Note: 
Since the Sony DSLR-A900 does not have an integrated flash or the built-in flash, then it triggers the flash dedication Sony directly, wireless, and only uses one dedicated flash unit Sony, becomes possible. While Sony has not created a module trigger the flash wirelessly dedication Sony-single, then you can choose two ways triggers: [1] Using two flash units and Sony's dedication to pair one of them in the hot shoe Sony DSLR-A900 as a master unit, or [ 2] Using the flash accessory wired trigger.
To trigger an external studio light with the Sony DSLR-A900, there are three ways you can take, namely: [1]ony DSLR-A900. [2] Triggering the slave studio lighting using Sony Speedlite flash hot shoe on the SonyDSLR-A900. Place in Manual mode with the beam of 1 / 16 or 1 / 32. Flashing lights that flash will trigger only once a slave studio lights. [3] Using a trigger module studio light with radio waves. In general, these modules use ISO 518 flash lamp holder which is commonly used by Sony's competitors. Change forms are available from standard flash holder Sony to ISO 518 standards are common, with Sony FA-HS1AM Hot Shoe Adapter. Please look at the details on the DSLR / T Accessory.
