Good God f/11 is slow. I'd say for photographing birds lenses that are so slow would be virtually unusable if you want to shoot at any reasonable ISO.
I take photos of bald eagles a few times each winter. 1/1500 shutter is a good starting point to get sharp shots. What ISO would I have to use to shoot wide open at 1/1500? Too high
