Just about everyone that has compared the lenses (under the microscope) says the ART is sharper across the zoom range.
Now under practical normal use (not in the lab) is the difference that Obvious ?
A Factory Nikon Refurb can be had for $550 vs $900 for a new Sigma.(I see no refurb sigmas out)
Witch would you choose and why ?
Thanks for your replies!
