Okay I'm nuts but read a few pretty good reports on it so i ordered one last night. I am going straight to Zion with it so next week i will post some shots and give you some thoughts on it. I also picked up the Sigma 150 2.8 macro and 1.4 converter to go with it. Also replaced my Zeiss 18 ZF with the ZF.2
Once again i'm playing the guinea pig role. Does this ever end.
BTW the Sigma 150 2.8 at F5.6 is stellar. F4 its really good and 2.8 its good but 5.6 kicks butt.
