I've bought 3 cameras this year the Sony Alpha A55 , Lumix G3 and the Fuji X10.
Of the 3 I would choose the Lumix G3.
Although I have two other m4/3 cameras , I have always remained unconvinced that the m4/3 format was going anywhere as the kit was small but not small enough and image quality was good but not good enough .
The G3 changed my mind.
Not only was the camera cheap - ish , it came with Lightroom 3 , the Jpeg quality was much improved and focusing is quick enough to enable shots like this with a lightweight lens (100-300mm)
