I posted some pictures from my trip to the Detroit Zoo on Sunday earlier this week. Well I had to go back today because when I paid on Sunday there didn't return my credit card to me. So I decided to give my latest addition to my bad out, a Sigma 2x HMS EX TC on my Sigma 70-200 F2.8. It was a lot over cast today so I had to use a higher ISO than I really wanted to, but I am very pleased with the results. Here are a few pictures from my 2 hours at the zoo before work today.
