You may have noticed that I don't really mount Panasonic lenses on Olympus bodies or vice verca. I prefer to mount native lenses on native bodies. I.e. Olympus lenses on Olympus bodies and the same goes for Panasonic. What I'm waiting for now is that pro body from Panasonic because I've been disappointed with the body selection of late. Aiming in the wrong direction for my taste. As I write this they have just relesed a press statement about the G5 but that isn't a pro body either.
Some might be wondering what I mean by a pro body. Well, the Panasonic bodies are made mostly of plastic and the feel isn't up to the Olympus bodies. The GF1 which was the first body on the market does however feel great. It's just been down hill from there on.
