Fusion: No image metadata

Maybe I'm missing it, but it doesn't look as though image metadata is being passed into Fusion at all. The sub-view is empty, and attempts to access Metadata with expressions or scripts fail. Examining the Metadata panel for my images does not show any of the metadata I need to see, either.
Attached is one frame of a test render from Redshift that carries metadata describing the camera.
