With keeping ISO on 200, the almost ten year old and only just 3.2 MP the KM Z1
make a decent pictures. No PP
I recently dusted down my Z1 and tried it again. I had very fond memories of it and it doesn't disappoint even now. Very good (slightly oversaturated) colour and very low shadow noise at ISO 50 or 100. It also suits my grip and find (as I did back in the time) I can hand hold it better than any camera before or since (1/8 sec at wide, 1/60 at full zoom).
I've started using it regularly again. It's up against a Sony NEX3, an Olympus EP-L1,a Canon SX30IS, and an old KM A200, and still holds its own for sheer fun and colour rendition! Am I mad? Maybe!
I don't find the 3mp a limitation provided you compose well and so don't need to crop. Shadows can be easily pulled up in p/p without noise, something difficult to do with a lot of modern cams.
