looking at the popphoto website i came across the test for the Sigma 24-70mm
UC and 24-70mm EX. according to the charts it appears that the $100 UC lens
is signficantly better than the $350 EX version especially with prints
around the larger size.
it also scores higher than the EX version on the photozone lens test page
however it is trashed on the photozone.de user input database.
is it a sleeper?????
