I have these photos in a local gallery: Solar Culture Gallery â€“ I Want You | Mark Hahn Photography The opening is tomorrow night. Let me know what you think of the images. The first two were taken with the Sigma 30 and the last with the Oly 17/2.8. I think the set shows what a nice pair they make. In the first two I get the nice, slightly longer than normal, perspective of the Sigma 30 and I swapped out to the 17 when I wanted something wider for the last.
