Trying out my new (to me) Sigma EX APO 70-200mm f/2.8 yesterday. I'm not a wildlife photographer but have been meaning to photograph these critters for some time and yesterday was my opportunity. In the near future they're being moved somewhere that they can be properly taken care of, and away from their current home in the tropical garden in the old Atocha train station in central Madrid.

These were all taken wide open, where the lens is decently sharp.

A couple of night-time long exposures with the 17-50mm f/2.8 in Siena, Italy. The second one is a stitch of two images as there wasn't quite enough space to get the tower in one.
