Sony announces A7 and A7R: first full-frame mirrorless cameras

This is the moment waited by everyone, a full frame mirrorless! A full frame mirrorless interchangeable lens! Sony has announced the A7 and A7R - the world's first consumer-oriented full-frame mirrorless interchangeable lens cameras. Externally, the two bodies are nearly identical and feature a pentaprism-like EVF housing, generous handgrip and plenty of manual controls. The differences are internal - sporting a 36 megapixel sensor, the A7R has no optical low-pass filter and is limited to contrast-detect autofocus, while the less expensive A7 has a 24 megapixel sensor with a low-pass filter and on-chip phase detection.

Both bodies are designed around the Sony NEX E-mount, though new 'FE' lenses are needed to take advantage of the larger sensor. They also feature a new BIONZ X processor, XGA OLED 'Tru-finder', 3-inch LCD, Wi-Fi connectivity with NFC, and 60p video recording. Existing lenses for Sony's NEX range of APS-C mirrorless interchangeable lens cameras will mount and work as expected, though the scene will be cropped (though Sony gives you the option not to do so if you can live with some inevitable vignetting). Sony Alpha lenses can also be mounted via either the LA-EA3 or LA-EA4, the latter of which includes SLT autofocus technology. See our first impressions report for more.
