Hi! I found 4 Sigma Objectives, all of them 70-300 4.0-5.6 APO Makro Super II (230 ) DG APO Makro (210 ) DG Makro (145 ) DL Makro Super II (155 ) and I don't know what is the best. OK, the last 2 I wouldn't buy. About the second one I read quite good critiques, like here: http://www.photozone.de/8Reviews/lenses/sigma_70300_456/index.htm But what about the first one? Does anybody knows this lens? Is it the same as the second one, just without "DG"?
