Just posted: Our review of the Sony Cyber-shot DSC-RX1. The RX1 is one of the most ambitious cameras Sony has ever built: a full-frame compact with a fixed 35mm F2 lens.

We've run the RX1 through our standard tests and looked into its performance and what this unique camera offers. Click here to see what we found.
