Nissin Di622 mk 1 and RF-603

I have one of these flashes and I've been pretty pleased with it.

It works well in iTTL on the camera (or via an iTTL cord) but I've had problems with it as a manual flash (running via a PC synch cord to hotshoe adaptor or on a Yongnuo RF-603 wireless trigger).

However, I read on Flickr that there is a FOC firmware update available for the Nikon version of this flash which would allow it to work with wireless trigger. I contacted the UK distributor (Kenro) and sent the flash to them last Friday. I got it back today (Wednesday) with the firmware updated, free of charge.

I'm pleased to say that it now works on the RF-603 and the hotshoe adaptor. I thought I'd post this here in case anyone else is having problems in this area, or anyone was considering this unit.
