Hi,
Does anyone know what the APO stands for (and what it does) for some Sigma lenses?
I have been having a look at the Sigma 70-300mm f/4-5.6 APO Macro DG (Canon AF) but its always £50 more than the none APO version.
What the heck is it? everysite I look at doesnt seem to show any different specs :|
