Hi There. I got a Triggertrap v1, a Nissin 466 flash and wanted to try some hi-speed flash photography. So, from eBay I ordered a PC Sync to (dual) hot shoe adapter, and a jack to PC Sync cable. Now the last piece arrived, the cable, and it doesn't go in the PC Sync socket of the hot shoe adapter. Here are the two objects: eBay - 3.5mm-Male FLASH PC Sync Cable for Trigger Transmitter eBay - PR-02 Studio Flash Speedlite Trigger 3.5mm PC Sync Port To Dual Hot Shoe Adapter Here's a quick collage of the two relevant parts: What I'm missing? Are there various PC Sync variant around? Different sizes maybe? What kind of connector I need to go in that socket? Many thanks!
