Problems with DMC-FZ20

After using it for about 11 months, I encountered some issues with this cam:

• Visible noise (grainy) at ISO above 200 and unusable at ISO 400
• A bit under exposure for most shots
• Focus hunting at telephoto end
• Image can look a bit soft although it's a Leica lens
• Electronic viewfinder is a bit too small and hard to see when dark
• There is no external TTL flash for this model
• Not wide enough for landscape photography, min 36mm

Visible noise at the dark sky. Shots was taken at ISO200 for 6 seconds exposure. Let's us look closer by cropping the above image...

Yucks! Can't imagine if the shot taken at ISO400.
