The Alphaa7 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.
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.
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.
