Thanks for warning guys. I was interested by this little beast as a small digital back for my M lenses and a possible successor to my good old Digilux 1 but if it has more shutter lag or whatever slowness than the latter it is a deal breaker for me i'm afraid.
Well, I wouldn't be put off by a couple of oldies like us! - it's sooo much faster than the Digilux 1 that you wouldn't believe it. There is lots of good press for this camera, and it's such a huge step forwards.
My remarks were about personal use for taking pictures of people in low light - I'd rather use the M8, but I'm sure lots would disagree quite radically.
Go and try one out - seriously, I'd hate to be responsible for putting anyone off. The G1 is a huge leap forward in so many different ways, using it to replace the good old digilux1 would be like replacing a trusty old ford fiesta with a new scirocco!
