A few weeks ago I bought a bridge camera "Panasonic Lumix DMC-FZ200", with which I am very satisfied by the way. But the built-in flash is sufficient only small claims, is too weak and has, like all built flashes, the "red eye problem". So had an external flash forth (Bg) for bounce flash. After a long search in many websites, I came to the Nissin Di466 MKII - please check specifications themselves. The Bg by Panasonic, or the well-known manufacturers, are similarly equipped and may well, or better, but totally overpriced. The selection of Bg support TTL and Samsung cameras (as well Qlympus, Leica) can be controlled, is quite small. The device, "Nissin Di466, MKII, for Four Thirds / Micro Four Thirds", makes a high impression, and especially fit my camera! It is properly controlled with appropriate and exposure controlled from the camera - with good results. The slave function, thus uncouple the unit and trigger through the built-in camera flash, also works, but not always !! Here the brightness and the angle has a role to flash. Unfortunately I can not verify that the the above expensive Bg better. Triggering by radio is, for lack of signal from the Lumix is not possible. The equipment is sufficient, all important functions can be affected. The illumination and range is good and sufficient loose "normal" claims. Whether the illumination absolutely correct to the corners is I have not checked, but there are no obvious problems in this regard. The disadvantage was previously only that one of my Accusätze (TKA, NiMH, 2700mAh) is not working. With GP, or TOP CRAFT NiMH accus it works and it is achieved a short charging time and rapid recycling. The enclosed Quick Reference Guide is insufficient, there is but as a side dish (small CD), or via a link, a German-speaking guide which is just sufficient. The flash head can be just tend not rotate. Nevertheless, for about 75 a good buy, I absolutely do not regret.
