For what it is needed to do, the Westcott FJ Adapter for Sony gets the job done. I use it for firing my off-camera flash and on occasion when I'm shooting faster than 1/250th of a second.
The only drawback (and this is something that Westcott needs to address) is that the adapter isn't as solid as it needs to be and sometimes a flash won't feel as secure as I feel it should).
From PROCAM's side, they were phenomenal. From assisting me in ordering, to the speediness of the delivery, PROCAM was the epitome of customer support. I will be glad to shop with them in the future.
