Thanks Federico, no offense taken. I've also defended my GL2s on many occasions since most people in the wedding industry are hard-core Sony users. But, I have no particular allegiances except to the client and if I can get a better but affordable picture with a Sony, Pannie or Canon, I'm interested.
Happy holidays to you also.

I love my GL2 but I have to tell you that yes the 150 has a jaw dropping advantage when it comes to low light. Save the GL2 for controlled environments and for weddings grap the 2000/150.

One more stop out of the GL2
 

When you are in low light with the GL2 put it in frame mode and use 1/30 sec shutter. The motion signature looks quite normal.

This should narrow the Sony's advantage in low light.
