I wanted a flash of expression FZ-150th To me to take a picture I had ordered the METZ MB24,36 and give the NISSIN, and tests made with these three, and the built-in flash. Bottom line, the Di466 was the best by far. I z..B. photographed against a white wall to test the illumination. The Nessin was the only uniform light distribution, which was MB36 as really bad, he drew a line of shadow on the wall, it looked like the photograph of a car headlight. The processing of NISSIN is good. Nothing wobbles because rattles nothing, and the battery compartment is very well resolved. I have in there Enerloop batteries, and I have never failed for lack of flash juice! I highly recommend this unit highly enough. A star deduction there for the description. Which should be better. Without a photographer friend I had maches feature, for example, probably never found out with the daughter flashes.
