Actually, maybe this is a deliberate decision made by Olympus. If you look at what Panny is doing, they are basically replicating what Olympus had done before with the 14-45 (the old Oly kit lens from E500?), the 14-42, 7-14, and now the 12-35 and 35-100. Its like panasonic sort of sorted out the question of deciding what focal length lens to manufacture by simply following Olympus' 4/3 road map. On the other hand, Olympus having done all that for their 4/3 system, now seems to be more focused on primes for the m4/3 range, leaving panasonic to take up the slack on the zooms. Could it also be that Olympus is trying to revisit the lens range in the old OM series? I do not if this is the plan or just how things happen to turn out. And by doing so, they help to provide some product differentiation between m4/3 and 4/3. I know it does not make sense in that you should have more zooms in the less pro range, but then again, the counter argument is that if u want things small and good, primes is indeed the way to go versus an equivalent zoom.
