Maybe not the best picture to introduce my new Leica lens for the GF1 but I liked how the clouds looked and thought it makes a nice picture regardless of the lens used.
One thing is certain though, only after you start using some good legacy lenses on the m4/3 cameras will you see their true potential. Even the highly praised 40mm Panasonic lens is very poor optically when compared to the Leica or the Voigtländer lenses. The contrast, the sharpness, the colors are all different and even my cheap Canon FD lens is superior to the native m4/3 lenses.
The only downside is that the new Leica lens and adapter weight almost more than the GF1 and 40mm lens together. It is worth however for the optical quality and also for proper MF ring around the lens instead of the stupid focus by wire system.
