Insects like dragonflies have hundreds of lenses on their eye surface.
Have cameras been built with two or more lenses for large field of
view ? |

You might be assuming that the insect eye is a bunch of lenses
focusing on one retina. It's more like an array of little eyes,
each with it's own lens and it's own retina.

There are lots of software solutions used with 4 or so conventional
digital cameras to give a simultaneous panorama. |

There is the Fly's Eye for detecting cosmic rays:

Yes, but "retina" is not really correct. There are only about seven
light-sensitive cells per facet.
There is a lot of interesting research on the insect visual system, for
exemple at my alma mater:
