Just Posted: an extensive update to our Sony NEX-6 preview. The NEX-6 is an enthusiast level mirrorless camera that features the high-resolution OLED viewfinder we first saw on the NEX-7 and builds on the capabilities that appeared on the recent NEX-5R. Click through for a link to the expanded preview, including six new pages of test data. We'll be adding more pages as we work towards the publication of our full review.
