I shot f/1.8 at 1600 the whole night. 1600 ISO. 1. 2. 3. 4. 5. I'm definitely pleased with the purchased. I have 30 shots that are absolutely keepers. I wasn't going to post them all, because I figured nobody could sit still long enough to take a look at them all. But if you'd like to see them, PM me. Any thoughts?
