Certainly true with traditional optics. I think computational optics will change things though - there's been research into using camera arrays for simulating a large aperture, for example. I don't actually know if this is physically feasible, but maybe in lieu of a single large sensor we simulate one with a ton of smaller ones (cool gifs: http://www.mit.edu/~sysun/MAS531_lightfield.html http://www.mit.edu/~sysun/MAS531_lightfield.html)
