I'm curious. If this Olympus 40-150mm f/2.8 rumor is true, is there anyone who would go for the Panasonic 150mm f/2.8 over this Olympus zoom? At the telephoto end, the size difference between primes and zooms isn't particularly big... In my mind, beyond 100mm, the value of a prime over a zoom is diminished for most purposes (depending on their aperture). Any thoughts on this?
