The Alphaa7R 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. 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.
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.
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
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.
