We noticed at least two curious “poblems” if not “conflict between Sony and Amazon.
1) Phil Askey from dpreview wrote: “Having spent a considerable amount of time producing previews of both cameras we were slightly surprised this morning to see full reviews of the NEX-5 on another sites who were apparently given production cameras (which we were promised but never received). We only received pre-production models and honored Sony’s request not to publish images.” Important notice: Dpreview is owned by amazon!
2) Amazon US is usually fast in offering pre-orders when a camera has been announced. After three days amazon is the only major shop in US to not offer the NEX cameras for preorder!
As you can see here, Adorama, BHphoto and RITZ do list the NEX cameras.
There is absolutely nothing on Amazon…..and did you notice the MicroFourThirds banner instead? Curious
Anyway I believe in both cases we only saw a comunication problem between the two giants.
