Review on Yongnuo YN320EX Flash Speedlte A7R II by Lorenzo Wood

ERROR OUT OF THE BOX! - Don't even try to use it in TTL on SONY Alpha a6. cameras! Go ahead and update firmware immediately! Now that you're done, you can enjoy this little wonder as intended! - Full TTL mode, good for about 90% after firmware update! - TTL master with other devices (identical). - Master radio control for most Yongnuo flashes (e.g. big ones) - Master flash control for any light powered remote flash of any brand - Control 6 separate groups remotely from it when used with compatible flashes, equipped with a Yongnuo wireless transmitter - Simple but detailed menu system for customization. This little marvel with its small size is perfect for Sony & body without oppressing it! Absolutely amazing features, everything you will ever need from Master Flash! You won't find anything better from an excellent brand that costs many times more! Definitely a WINNER in my book! WOW! The one and only problem is the firmware, so Yongnuo must include a printed notice to update the firmware immediately if the device does not have the latest firmware! But everything else about this little flash is amazing! Easy 5 Star Rating!
