I am trying out an SD Quattro. I like that it shoots 4:3. There can't be a better built $700 camera. It's built like the proverbial tank. It actually works better in manual focus I think. This is with the 18-35 1.8 zoom. It also lets you save the files at DNG if you don't want to use Sigma Photo Pro. I kind of like SPP. Anyway the first one is DNG and the second is in SPP in monochrome mode. I did manage to stop them from rolling in some kind of horrible smelling poop this AM. They weren't too happy about that.
