> One of the things I’m looking forward to trying when I get my Sony A7 is to see how well my Nikon lenses work with it via a lens adapter and what it means in real-world shooting. In particular, I’m looking forward to pitting the bodies head-to-head with the same glass and seeing what happens.

I wonder if the A7 will start something like the Canon 5D did with DSLR videos: cross-system lens adaptability. And if it becomes a reality, there will be a spike on third-party lens adapter production.
