The Alpha a7R Mirrorless Digital Camera fromSony 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. Differing from the full-frame Sony Alpha a7, the Alpha a7R omits the low-pass filter from its 36.4MP sensor, thus optimizing its high resolution, detail-rich imaging capability. In addition, the sensor features a new gapless lens design to increase corner-to-corner light collecting efficiency.The standard ISO sensitivity range of 100-25600 provides rich saturation in bright light and clear, low-noise images in low-light situations.
The new BIONZ X image processor offers fast processing and operation speeds including fast, intelligent autofocus and 4 fps burst shooting. 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.
The new autofocus system is optimized for the full-frame sensor including flexible spot focus areas in addition to multipoint, center-weighted, and zone focusing. Manual focus assist can be optimized for full-frame or APS-C-format shooting zones and 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 allow for viewing of still images on ultra-HD 4K television. The 3.0″ tilt-able LCD has a 1.23M-dot resolution and WhiteMagic technology for better visibility in bright light. A high-contrast 2.4M-dot 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 makes 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 E-mount lenses as well as 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.
