Sunday Afternoon Hummingbird II AKA Auto ISO Flaws

I grabbed my newly repaired/cleaned/adjusted 7D and set it for speed, as in hummingbird wing speed. I wanted to lock in a fast shutter, so I used "Auto ISO" to keep exposure reasonable. That works great until your shot includes shadow and the camera goes ISO 3200 or higher. Note To Canon-Let us set an upper limit on that feature please... Top shot is not a hummingbird, it shows the noise from the 3200 ISO setting.

But otherwise I had some luck with the fast settings.
