Just posted! Our new lens review of Tamron's latest baby, the SP AF 70-200mm F2.8 Di LD (IF) Macro. In the third of our epic four-part series of telezoom reviews, we take a look through the viewfinder using a lens said to inherit its 'product concept' from Tamron's highly regarded 28-75mm F2.8. So does this young pretender really inherit the same compelling mixture of fine optics at a bargain price, and provide a challenge to the camera manufacturers' own fast telephoto zooms?
