8etty, I suggested the similar things under other subjects here. I think oscar gonna kill us because we're trying to make things complex than ever.
But I partly agree with you.

I agree about having lenses which emulate the distortion, which would be impossible to do in post, but the rest, such as different glass coatings for lenses, different glass, I think that would be better left to do in post.

I like the idea of having lens systems that work like their real-world counterparts, but due to their purely virtual nature are also not limited to what a real lens can achieve. Yes a 300mm lens focussed one inch away from a cockroach would have a DoF of about 1 nanometer but that's neither here not there.

As long as it was true to what a 300mm lens would do if you removed the physical constraints of lens construction then that would be good for me.

Yes,
I agree too, with this idea.
It could be possible to import and export diferent lenses.

Well, If you would like to build a full blown object simulator, then probably yes. But such a thing would be useless for evryone except a few optical engineers anyway.

In fact, in CG it is easier than everywhere else to build a "perfect lens" by definition. This should be done by defining the lens properties in a mathematical way. There is no need to waste render time by actually shooting rays through dieelectrics
