I had a meeting near the Racine (Wisconsin) zoo that Ben mentioned in a previous thread. Didn't have any idea when/if I could make it, but I did have a small window of opportunity to make it so I went for it.
Based on Ben's description of it, I took only the 50mm f/1.8 and the 300mm. It was really quiet - I only saw 5 other people - and most of the animals were indoors.
Sorry if these images look somber, but a quiet zoo is a sad zoo IMO and it affected the way I shot. Nothing against the zoo - it was actually pretty clean and well kept, just quiet due to the weather. Please visit and donate if you are in the area.
