Just tossing it out there, though I'm sure someone already thought about something like this. Sure, its only a 2x zoom... but really, what this lens could be (barring physics making it too large... though maybe it wouldn't be THAT bad since it's only a 2x zoom) is a true alternative to owning all of the most popular focal length primes. The f2 is close enough to being the standard f1.8 of most of the primes which would allow for a lower ISO and better DOF than the Oly 12-40 2.8 today, and if the IQ could be, lets say close to the Panny 20 at f2, it could be a really interesting lens. I'd be pretty happy to have one lens that could basically replace an Oly 12 F2, Panny 14 2.5, Leica 15 1.7, Oly 17 1.8, Panny 20 1.7, Panny and oly 25mm. True, the IQ would likely not be as good as the Panny 25mm 1.4, but if it was in the ballpark, would you consider it? Anyone here who has a better understanding of lens physics, please go ahead and bring me back to reality and give me an idea of how ridiculous this lens would be in terms of size. If it could be no bigger/heavier than the Oly 12-40, that would be sweet... but again, I have no idea if this is even physically possible.
