Photokina 2010: Sony has announced a firmware update for its NEX-3 and NEX-5 APS-C mirrorless interchangeable lens cameras. Version 03 addresses a number of widely-expressed concerns about the user interface as well as allowing autofocus using the 14 Sony SAM and SSM lenses with built-in focus motors. It also allows the aperture to be set for video shooting. Given that the update aims improve many of the things we criticized in our review, we will update our review to reflect the changes as soon as we've properly tested the camera's revised behavior.
