Denny,
I've never had much of a low light issue with the A1, and I love the picture. It's worth really digging into the settings to get a good picture and it can be done. Try the PFVIsion preset. It's like turning on a light. Ask GM Elliott. He bought an EX1 to replace teh A1s and sent it back becuase it just wasn't that much better. I love mine. Now the 5D MkII is a whole different story. It is magic.
Bill
