Nothing really, other than a slowdown from wasted computations. Photons 
just light up surfaces and media. A lens doesn't have a surface that is 
very diffusively reflective, and the camera can't "see" the photons. 
Lens flares are specular reflections of the light source, not caustics 
on the lenses.

I guess you could make every single object in the scene interact with 
photons, use reflection with a fine-grained normal on all diffusely 
reflecting objects to scatter the reflected photons, and put a screen 
with double-illuminate between the camera and the lenses. I don't know 
if this would work, if it does, it would require insane numbers of 
photons and wouldn't have any advantages.
