It's expensive for the power it produces.
The manual needs a manual.
Any mimnum repair on this puppy (since it's all board will be a C class) about 150 dollars or 50 % of it's cost. At least we never got a quote less.
Still only a guide in the 120 category, same as the old Vivitar 285.
Use the five batteries with Kodak (Panasoonic) OXY-DIGITALS and you will have a meltdown. (Reported Problem)
Super fast accelerators MAY burn this puppy up. Really doesn't have much heat dispersion inside the case. So you should not try to blow the thing up with continuous bursting.
Camera settings, many shots underexposed if tyou forget and mix up the matrix, center and spot setting with the four flash settings.
Some owners also reporting inconisitency in the flash power, ( could be a host of reasons, like six cooks and one pot of soup, between the camera settings and the flash settings many get confused.)
So thats the darkside... just so things are fair. This is a flash that has a lot of features and is useless if you don't make an attempt to learn them. The book is annoying but does have answers. Written in Martian for most but the majority swear the strobe is out of this world anyway.
And last but not least two questions to users.
a) If you shoot QUOTE "manual settings for the flash all the time" why buy the NIKON or the Canon for that matter? It seems some prefer ( I do Manual settings but I have 200 wattsecond units)
