I just read that Olympus will probably make lens for Sony NEX and they mention a micro zuiko 400 f4 lens. Olympus to Supply Sony with Lens Parts; Olympus 400mm f/4 Lens Coming for Sony Alpha? This, for me, is a really great news. Because we would have it for micro four thirds, right? If Olympus ever builds something for NEX and not for micro four thirds, my love-hate balance for olympus would get very unbalanced. 400 mm... cocodriles, here I go!
