So... anyone can point here what is wrong :
Code
Filename: dsc06862ab.jpg
Rozmiar: 107Kb
Rozdzielczość: 1200 x 674
Camera used: SONY DSLR-A300
Orientation: Horizontal (normal)
Focal length: 18.0 mm (35 mm equivalent: 27.0 mm)
Aperture: f/4.0
Date/Time: 2011-01-16 19:32:39
Exposure time: 30
Lens F-Number: f/4.0
ISO: 100

Like what you would change ?
So i will have point to start from

Only thing i can suggest is upping the ISO and bring down the exposure time. Open up your aperture too and focus via live view. Or slightly away from infinity.
