This is the Olympus FL-40 external flash. This is a very very good flash, put it on you hot shoe or the handle and plug it into you camera and away you go. It is a TTL flash and as a very good range. The guide number is 40 for Tele Zoom an 26 for wide zoom. The head will turn almost 360 degrees and will left up to shoot bounce off the ceiling. It uses 4 AA batteries and is very good on batteries. The down side is its cost, very high.
