But when I look at their pro lenses, I don't seem to see a size advantage. Seems that when you want to go to pro lenses, you might as well stick to pro bodies. For me, having such a small camera would only make sense with small lenses as well. And we all know that in order to have pro lenses with large aperture, they need large pieces of glass. So for now I'll just stick to Nikon and when I want to go light, use my X-10. Now we talk light.
