Just to get opinions from all phototaking lovers...

I wish to change my EOS 550D for a more compact and lighter camera. However I still want to take wonderful photos as how 550D does. My friend recommended me Panasonic Lumix and I am eyeing on GF6 at the moment.

I never try Panasonic before so not sure about their performance level. My only concern is to shoot fast moving objects (my son... ) and night portrait..

I never upgrade to any lenses kits for my EOS. Right after bought the camera and being as a parent myself. That is why I need a lighter body. 660D is too bulky for me.

Other suggestions are:-
1. Olympus E-PL5
2. Sony Alpha NEX 3
3. As stated above, Panasonic Lumix GF-6
4. No, keep EOS 550D

Great thanks.
