I don't see noise. I see some lovely portraits!
I've had 2 x LC1's and a Digilux 2. I sold the LC1's and kept the Digilux 2 (for the red dot I suppose😱) but in all honesty the LC1 feels better in the hand.
Like many others I don't think it imagination, I think that there is something special about LC1/Digilux2 files.
