What do you think of the video?
Meanwhile, I'm still waiting for my order. I ordered mine from B & H Photo, and they said the order was delayed because they received the cameras today but the free accessory pack hasn't arrived. To expedite the shipping, they split up my order and upgraded the shipping to 1 day at no cost. Hopefully I'll get it soon. At least one reader who ordered from Amazon said that his order was due to arrive today (release day in the US).
