Rob Skoetch from ThePictureDesk (Click here) has been the first person to post some image samples taken with the new Sony NEX-7 and the new 50mm f/1.8 OSS lens! Those are not full size pictures but he said he will soon add them on Flickr (Click here) where you can already find A77, A65 and NEX-5n full size image samples.
The NEX-7 is probably the most requested and preordered of all new Sony cameras. It will be start shipping from early November. This is a short list of stores I found where you can preorder the camera to be the first on list (otherwise your risk to get the camera in 2012 only):
Body only: Sonystore US, Amazon US, Adorama, Sonystore Canada and in Europe at Jessops and Computeruniverse.
With 18-55mm kit lens: Sonystore US, Amazon US, Adorama, Sonystore Canada and in Europe at Jessops.
I have seen that the most requested lens to put on your NEX-7 is the Zeiss 24mm f/1.8 which you can preorder here: Sonystore US, Amazon US, Adorama, Sonystore Canada.
The 50mm f/1.8 can be preordered: Sonystore US, Adorama.
As you see there is no preorder option I found in Europe (a part of the NEX-7 at Jessops and Computerunivers). Feel free to comment this post with links to shops accepting preorders! This will help other SAR reader to get thei NEX-7 and lenses as soon as possible!
