From how far away can you hit someone with an evocation?

But lenses are centuries old, and in this example, if I'm understanding it right, the fiber optic cable is basically working like a lens. It basically glass bending the path of light, I believe, so it might be resistant to hexing the same way lenses are. Anyway, I think the idea is that there's no electronics involved, which is the most vulnerable sort of technology. Everything is either mechanical, or light being bent by interaction with physical materials.

It's not about how it's being used, it's about it being new. Clearly, the magic making things not work doesn't give a damn about logic or guns would be immune. They aren't. It's a conceptual, not logical process. Is it new? Yes. Well then it fails.

Actually, a fiber optic cable works like a mirror, not a lens. The fiber is a pipe and the light bounces of the inside of the outer surface of that pipe - like an infinite series of mirrors.
With a lens you are still looking directly at your target. When you you use mirrors you are looking at it indirectly. An evocation needs to follow a straight line to the target. Anything else is thaumaturgy.

Hmmm. Old things are now made of new material. Earlier, you mentioned a evocation sniper with a telescope. If the lenses of the telescope are glass then it's okay? If they are made of Lexan then it's not?

If that's what's fun for your group, sure, that works.
