Just Posted: Sony NEX-3N hands-on preview with real world samples. We've had a chance to use and shoot with a NEX-3N and, now that Sony US has announced the camera, we can publish our look at the latest model. The 3N is the fourth entry-level NEX camera and the smallest so far. Despite this, it includes most of the features of its predecessors. We look at what has been added and what it lacks, compared to last year's NEX-F3.
