At JimBuchananSpace you can find the pictures and description of the new NEX-7 Palm Grip. Smart Idea!
Chris Townsend posted his personal NEX-7 review: “Is the Sony NEX 7 the best camera for backpacking and hiking? I don’t know. It must be one of the best though, given the low weight and bulk and high image quality. It’s definitely a camera for photographers who want the best results and who are likely to make large prints or have images published.”

A weird thing is that Amazon says the Zeiss lens has still not been released… :)
