Bernd, I saw this portrait earlier in your gallery and I immediately fell in love! You have clearly have a wonderful rapport with your portrait subjects. The colors are fantastic and the sharpness looks good to me.
I'm guessing that this was at some sort of festival or fair - at a shooting gallery game?
Johan & Bill:
Yes, the pic looks sharp but I guess that the 20mm Panny got the wrong focus point. So I used the 'magic brush' in Lightroom3 to sharpen the eyes a bit and the white hairs from the beard in some areas.
The more I shoot with the Pen the more i like the colours of the little cam. The pics from Sicily were the start. But the b/w conversion in LR3 plus the new 'Grain' feature is smart......No wet fingers from the developer....
