I’ve had this flash for some time now, and whilst initially impressed I’m getting slowly more disappointed with it. It seems to consistantly underexpose photos. I’ve no idea why. There are certain combinations of having the cameras ISO on auto and matrix metering enabled where the flash will fire but it always seems to be at 1/128. Changing the iso to manaul (and keeping all the settings the same) fixes it. How does that make a difference? Another fix is to enable spot metering. I’m very confused. It seems most problematioc in contrasty areas or when I focus on something that is black. I can’t recommend this flash unfortunately. I’m now looking for another. I seem to keep spending £100 or so on flashes that arent perfect. MAybe I should bite the bullet and just get the sb910…
