want to use it for macro's mainly.
flash is away getting fixed so cant get you any measurements.
I have a 500 DG ST. So not sure if this is applicable.
Nice flash though I would get SB600. I think the Sigma would be close to $260 australian on ebay including shipping to Aus
The results are good, if you learn what to do. I dial down the power (exposure) I traded a 35-70mm f3.5 and paid 70 bucks for use on my Coolpix 5000 at Whiltons.
Comparing to (I do not have SB800) my main flash a Nikon sb-80DX (the former top
model) on my D100, with everything automactic its not as good in portraits, over exposed. For small room full of people just as good.
For a marginal $100 saving why bother. My opinion.
It great for my coolpix, no difference to SB80-DX, but on a SLR - you need to fiddle to get the results the Nikon Speedlights would give you out of the box, without looking at the manual.
For Macro I think you need to fiddle with the setting irrespective of Sigma or Nikon, also on or off camera, so just for Macro I would say it should be ok.
But who uses a flash "JUST" for macro
my 2 cents worth
