Having recently spent a bit of money for the sigma 17-70 I have my set of lenses in a pretty good place right now, no L glass or anything but good enough for my purposes and cash flow at the moment. I do however need to get a good flash in the near future however I don't necessarily have the cash I would like to spend on it.
My question:
Would one of the older model flashes such as the Vivitar 285HV be suitable for flash photography or would I just be better off saving and then springing for a sigma, the 430 or 580?
