Hi All, I wonder if any of you have experiences of either the Sigma 70-300 f/4-5.6 Apo Macro Super or the Tamron 70-300 f/4-5.6 LD 1:2 Macro AF lens - or preferably both. Which do you think is better in terms of optical and build quality? They cost roughly the same, but the Tamron's macro function can be engaged through a broader focal length range (180-300 mm), whereas the Sigma's is fixed at the longest end. Any experiences?
Thanks: Peter Farkas
