Hi All! While I am still looking for a used Sigma AF 100-300/4, I found, that according to Adorama, there are two versions of it with the only difference that one has an additional designation "DG".
http://tinyurl.com/d88xt http://tinyurl.com/79w55 The specs are practically the same with a slight difference in the length (2.5 mm) and weight (40 g). Sigma website doesn't indicate the "DG" version for this model. http://www.sigmaphoto.com/lenses/lenses_all.asp So, is it Adorama's error, or slowness of sigma web-site update? (in any case, neither is in stock). Does anybody know if DG version of this lens exists or will exist soon? Thanks, Igor
