I "played" with it at Dan's on Saturday - It's a very impressive camera and feels very 'substantial'. I personally don't like liveview only with no viewfinder though, but it works OK. The LCD seemed very bright and easy to see. Supposedly they are coming out with one with an EVF.
I loved how the HD video has autofocus and IS, something the $2,500 Canon 5D, Mark II, Series 12, Version 612, Batch 37, Color ID 12, Model 75 doesn't do.
Sample video here.Yes - I have a problem with some of these naming conventions these companies use.
