After having a horrible time with sigma repair a few years ago, and not being to impressed with their IQ or build, i swore off sigma forever. Looking at their new 35mm, and reading what Roger has said about the apparent sigma company turnaround, and very kind words for this lens, i'm very strongly reconsidering.
in fact, i'd said i'm 90% sure i'll buy this lens in the next week or two. maybe later today. ?
