looking for opinions on the older (2004) sigma 18-50/2.8 lens and the sigma 18-50/2.8 macro version (started production in 2007?)
the price difference is making me question if the later is worth the extra $175 considering it is only a 1:3 macro and probably wouldn't be of much use - i do most of my macro work with my sigma 70-300 dg apo 1:2.
any sample pics or thoughts from users who have tried both would be much appreciated.
thanks!
