This is probably why the older ones were so cheap on BH. I got the older version but only when they were backordered so I feel like I'm going to be waiting awhile for them to arrive.
At F2.8 these are a bit slow. The 19mm and 30mm are simply repackaged from the previous version. Although, having all these lenses with 46mm thread makes it easy to exchange filters. The ones that have 37mm like the 45mm Olympus I use a step up ring. These Sigma's are nice to look at ;-)
Any better?
Please try to add formatting, and photos of each lens.
