since that lens is made to draw a much bigger image (for a bigger senser) more light is lost inside the camera around the m4/3 sensor. In other words, light bounce back and forth inside the camera body. The consequence is that the image looks soft, specially on very pale objects and immediately around it (a halo effect).

Interesting point about light bouncing inside the camera body. Everything there is black, at least on my camera, but in high contrast situation there will have to be some reflections.

The color inside body cameras is said to be black. But actually, it's dark a grey color in North America (and a dark gray colour in UK). In order to appear so, that means that light is partially reflected. That explains the "halo effect" that I was talking about (on and around very pale objects).

If ever Panasonic and Olympus want instant sharpness improvement on their m4/3 cameras, they just have to start using really black coating inside their cameras. Unfortunately, users will start to complaint that these new models attracts dust more than the previous ones (simply because dust will be more obvious)...
