Spent the day, (Monday), at the Zoo with out of town family. Still a bit warm here in Phoenix, but manageable. A6000 and 55-210mm worked fine for most shots but anything at the 210mm in the dark was really a stretch for this lens. If I did longer shots more frequently, I would have to get something with a much better F-Stop. And I had to switch over to DMF whenever there was a fence in the way.
