We asked Sony whether the A7s would have a body-plus-lens kit available at the time the camera goes on sale, but the company said it didn't have any details to share on that at the moment. Still, chances are there will be one -- after all, that's sort of standard with camera sales nowadays. The availability announcement of the Alpha A7s comes alongside the introduction of the Cyber-shot RX100 III, as Sony continues to expand its camera lineup with a little something for everyone. Of course, the A7s is set to face a little more competition than its cousin the RX100, with existing options like Panasonic's Lumix GH4 and others looking to also get a piece of the 4K pie.
