Used the Q3 on my first job and all went according to plan. The only small hiccup was with the cable I was using to trigger the flash, the 3.5mm plug didn't fit too well in the socket, so I've ordered a cable with a 90º plug to see if that's an improvement. The flash is easy to use and feels well built. To get the best out of this flash you'll also need the QPRO TTL Wireless Flash Trigger, these are brand specific and I couldn't find one for Nikon available in Canada, but managed to source one from the US, hopefully it will arrive in the next few days so I can do more tests. Overall, I'm very happy with the purchase.
