I have the Olympus M. Zuiko 14-42mm lens, and was wondering if anyone switched from that to the Panasonic 14mm prime. I have the 20mm prime, and will likely get the upcoming 45mm/50mm from Olympus. On the wide end, aperture wise the 14-42 goes to 3.5, so there's not a huge gain with the prime at 2.5. I recognize the size advantage, but I'm wondering if anyone else has made this change and whether they thought it was worth it. I'd love the new supposed 12mm prime from Olympus, but it looks like it'll be out of my price range. Thanks!
