Just Posted: We've had a chance to use the Sony Alpha NEX-6 with its 16-50mm F3.5-5.6 power zoom kit lens and have prepared a hands-on 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. Does the addition of a mode dial and the Quick Navi interface make for the most coherent NEX camera yet? Read our preview to find out.
