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.

The A7 will be sold in a body-only kit for $1699 or with a new 28-70 F3.5-5.6 OSS lens for $1999. The A7R is not bundled with a lens, and is priced at $2299. Both cameras are expected to ship in December.

Press Release:

Sony Unveils World’s First Full-Frame Mirrorless Cameras ¹

New Sony A7 Series Are World’s Smallest, Lightest Full-Frame Interchangeable Lens Cameras ²

SAN DIEGO, Oct. 15, 2013 – Sony’s new A7 and A7R digital cameras are the world’s smallest full-frame interchangeable lens models ².  Highly anticipated by professional photographers and imaging enthusiasts alike, the two new cameras offer an unmatched combination of creativity, customizability and portability.

The A7R model features a 36.4 effective megapixel 35mm Exmor® CMOS sensor – the highest resolution sensor in the history of Sony’s A line – with no optical low pass filter for added resolving power and increased image detail.  The A7 model boasts an impressive 24.3 effective megapixel 35mm Exmor® CMOS sensor and an innovative fast Hybrid AF system. 

Each camera is equipped with advanced imaging features including a powerful new  BIONZ® X processor; fast AF capabilities; a clear, bright XGA OLED Tru-finder, full HD 60p video recording, Wi-Fi® and NFC connection, dust-and moisture- resistance and more.

“With these new A7 camera systems, Sony has completely redefined the look and feel of a professional-grade digital camera,” said Mike Kahn, director of the interchangeable lens camera business at Sony Electronics.  “The A7 and A7R cameras are significantly smaller, lighter and more portable than any other full-frame interchange lens camera yet deliver image quality, power and performance that professionals and enthusiasts crave.”

Both cameras feature full customization and control to meet the needs of the most demanding photographers.  There are 9 different customizable buttons and 46 assignable functions that can be adjusted based on shooting preferences, including fully customizable front and back dials, a rear control wheel and an exposure compensation dial ³.  Users can preview all changes to photographic settings in real-time on the high-contrast, 2.4 million dot XGA OLED Tru-Finder or the high-resolution tiltable 3” LCD screen.

The new cameras share a powerful new BIONZ X processor that accurately reproduces details in textures in real-time via extra high-speed processing capabilities, and allows for exceptional low noise performance in all types of lighting conditions.  Additionally, the powerful processor combined with the advanced, high resolution sensors allow both cameras to shoot pro-quality Full HD video (AVCHD progressive, 1920x1080p @ 60p) with richly detailed colors and ultra-low noise.

Clear Image Zoom has been enhanced for video recording as well, allowing for powerful close-up shots without sacrificing pixel count.  Other pro-style movie features include an audio recording level control and display plus a “live” HDMI® output for passing through video to an external monitor or recording device.

The new cameras both have on-board Wi-Fi and NFC capabilities for instant image sharing and transfer to compatible smartphones and tablets.  The A7R and A7 models can access Sony’s platform of PlayMemories™ Camera Apps, allowing users to add new effects, filters, utilities and more.  This platform includes new ‘Multiple Exposure’ app, which automatically combines sequential exposures into one creative shot, and ‘Smart Remote Control’ ⁴, which allows for direct control of exposure and shutter speed from a connected smartphone and is particularly useful for self-portraits or group shots ⁵.  Find out more at www.playmemoriescameraapps.com .

The new A7 and A7R cameras each have a tough, magnesium alloy build and are dust and moisture resistant for standing up to some of the toughest weather conditions.
