how good could the picture be from a camera that was the size of a fly's head?
Assuming the technology that formed the photon detectors was as good as possible.
I was just thinking it might be a bit fuzzy.

what is the smallest camera now, and how good are the pictures that it takes?
I would think the smallest camera would be a pinhole with a bitsy CCD behind it.
It would. Cameras can definitely become diffraction limited.

Here is a 2006 blog entry with picture about a CMOS camera that is 2.1 x 2.3 mm. They don't show any example pictures.
In the future, who knows, really.
We now know the diffraction limit isn't really a limit, if you use metamaterial hyperlenses.
