Akihabara posted a set of new images and the video above directly from the Sony booth in Yokohama! You can see tons of new cool stuff like the A77 + battery grip, the Sigma 30mm E-mount lens, the professional NEX videocamera the Zeiss CP lenses for Sony and more!
P.S.: Sigma should have done the 30mm lens as fast as the [shoplink 5450]30mm f/1.4 lens which is already available for Alpha mount[/shoplink]. That would be a nice lens!
Also DC.watch posted a set of new images from the booth.
