In August 2013, Sony announced the first model of the ILCE mirrorless camera with E-mount, electronic viewfinder, contrast-detection autofocus and Multi Interface Shoe, the ILCE-3000. In October 2013, two full-frame E-mount cameras were announced, the ILCE-7 and ILCE-7R.
The "ILCE" designation stands for Interchangeable Lens Camera with E-mount, replacing the "NEX" designation used for former E-mount cameras. As "ILCA", this naming convention will also be applied to future A-mount cameras, thereby replacing the former "DSLR" and "SLT" names.
Sony NEX-3 also the NEX-5 NEX-7 NEX-6 are the first Sony ILCE 2010-2013 
Sony Alpha ILCE-3000 (α3000), with the price less than $350, the camera can only autofocus using contrast detection; it has no phase detection autofocus, no SteadyShot stabilization and no vibration dust reduction, all of which DSLRs commonly have, but has Bulb mode for night photography. It is a DSLR-like body, so it is bigger than the other ILCE cameras.
Sony Alpha ILCE-5000 (α5000), with technical specs that differ little from the α3000, with 20.1MP and Full HD video recording ability. The significant changes relative to the α3000 are an upgrade of the imaging processor from Bionz to Bionz X, as well as the inclusion of near field communication and Wi-Fi, which leads Sony to bill the α5000 as the “world’s lightest interchangeable lens camera” (8 ounces) with Wi-Fi connectivity. The MSRP price is about $600. The camera is actually the successor to the Sony NEX-3N and has a NEX-like body.
Sony Alpha ILCE-5100 (α5100). Released after α6000, this is an updated version of the α5000 with a 24.3MP sensor and on-chip phase detection, the same as the α6000 but in a compact body like the Sony NEX-3/5 line. Sony claims that it is the world's smallest interchangeable-lens camera with an APS-C-size-sensor and a built-in flash, but no electronic viewfinder.
Sony Alpha ILCE-6000 (α6000). The successor to the NEX-6 and NEX-7 cameras. Has an electronic viewfinder and a Multi-Interface hot shoe.
