I went to a circus a few days ago with only one thing on my mind, to take some low light action photos lol. As expected I couldn't really freeze the action and got quite a lot of motion blur because of the slow lens I used but I was a lil bit surprised by how well my camera handled those high ISO shots. All pictures below were taken with 17-85 f/4-5.6 IS USM lens on a EOS 40D body and I used ISO 1600 and 3200 only for those shots. 1. 2. 3. 4. 5. 6. 7. 8.
