What's NEX? Sony Alpha a5100 first impressions review
As Sony introduces the Alpha a5100 interchangeable lens camera, it officially leaves behind the NEX moniker its mirrorless line originated with. The a5100 picks up where the NEX-5 series leaves off, combining the 24.3 megapixel APS-C CMOS sensor of the a6000 and the more compact footprint of the NEX-5T. The a5100 also inherits many of the a6000's good qualities, including its impressive autofocus system. The a5100 also one-ups its big brother by offering 1080/60p video at 50Mbps. We took a hands-on, preliminary look at the a5100.
