enko Teleplus HD C-AF 2X DGX teleconverter was attached. This photo was made hand held through a window from inside the house. F/11 is wide open for this combination of lens and teleconverter. The F6.3 listed is incorrect and two stops should be added. Auto focus was used. The combination of lens and telephoto converter confused the metering with a resulting very high ISO.

I could not identify the smaller birds until I stacked the extenders to get 1120mm. I guess the distance to be about 300 meters. I was not permitted to get closer.
