The Alpha a7 Mirrorless Digital Camera from Sony incorporates a full-frame Exmor CMOS sensor into an E-mount body thus providing the light gathering capability and detail-rich imaging of a full-frame sensor with a compact, lightweight, and versatile mirrorless, interchangeable lens camera system. The 24.3MP sensor enables high resolution images and low light effectiveness with its standard ISO sensitivity range of 100-25600. The new BIONX X image processor offers fast processing and operation speeds such as 5 fps burst shooting and front-end LSI (large-scale integration) improves the early stages of image processing resulting in more natural details and richer tones. 14-bit RAW output preserves the detail provided by the sensor.
An enhanced Hybrid Autofocus system combines a 117-point, phase-detection AF system with a 25-point contrast-detection system for high speed and accuracy. Flexible spot focus areas in addition to multipoint, center-weighted, and zone focusing contribute to its functionality and manual focus assist can be optimized for full-frame or APS-C-format shooting zones. New Eye AF Control provides highly precise eye-detection for shots that place the focus directly on the subject's eye, even when they are partially turned away.
Full HD 1080 video capture with 24p/60i/60p frame rates is supported in both AVCHD and MP4 codecs. Uncompressed video can be recorded off-camera via an HDMI connection, and both built-in and external stereo recording is available. HDMI and wireless output allows for viewing of still images on ultra HD 4K television. The 3.0" tiltable LCD has a 1.23M-dot resolution and WhiteMagic technology for better visibility in bright light. A high-contrast 2.4M OLED electronic viewfinder provides 100% coverage, a wide viewing angle, and features the same 3-lens optical system used in the Sony a99 DSLR.
Built-in Wi-Fi and NFC capability enable easy wireless transfer of images as well as remote shutter control from smartphones and tablets. Remote Control via a USB connection enables still photo adjustment control and now includes video capture control. The Quick Navi Pro interface system can display all camera adjustments on the LCD for rapid setting changes when needed.
The advanced Sony Multi-Interface shoe expands compatibility options for flash, microphone, and other accessories, and as an E-mount full-frame camera, the Alpha a7 is compatible with all present APS-C sized E-mount lenses in APS-C Crop Mode as well as the new E-mount full-frame Zeiss and Sony G-series lenses. Lens mount adapters with a tripod mount are also available to use A-mount lenses on E-mount cameras and an optional dedicated battery grip enables stable extended shooting and vertical orientation stability.
