Product Description
-------------------
Sony ILCE7B Full Frame Compact System Camera Body (24.3 MP, 117
Points Hybrid AutoFocus, 3.0-inch Tiltable LCD, 5 fps, XGA OLED
Tru-Finder) - Black. Operating temperature is 0 to 40 degree
Celsius. The camera display does not automatically switch from
the LCD screen to the viewfinder: The eyepiece or viewfinder
sensor is automatically disabled when the
FINDER/MONITOR(FINDER/LCD) is set to Monitor (LCD). Therefore,
the camera display will not automatically switch looking through
the viewfinder with this setting. Having the LCD screen active
all the time gives the Live View function priority, which helps
in achieving better compositions on a low or high shooting
position. To switch to the viewfinder mode, press the
Finder/Monitor (Finder/Lcd) button on the camera. Check on the
following if the display still does not switch after sw to
viewfinder mode: Make sure that the eyepiece or viewfinder sensor
is clean. Wipe off dusts or anything that might be blocking or on
the sensor. For cameras with tilting display screens, in some
cases, light reflection can activate the eyepiece sensor to
switch displays. Set the Finder/Monitor (Finder/Lcd) setting to
Monitor (LCD Monitor) to prevent the camera from sw
display automatically.
Review

From dpreview.com:
If there's one thing that you can say about Sony's digital camera
business, it's that they've experimented with many different
concepts. From SLRs with dual autofocus systems and Translucent
Mirror Technology to its NEX mirrorless line-up, Sony has gone
down virtually every avenue in digital imaging. Its latest
products - the Alpha 7 and Alpha 7R - may be the most exciting
products to come out of the Sony labs in some time. The company
has managed to create full-frame cameras which are about the same
size as the Olympus OM-D E-M1. In other words, the Alpha 7s are
much smaller than their full-frame interchangeable lens peers
(such as Nikon's D610 and the Canon EOS 6D), an achievement made
possible primarily because they're not SLRs.
In addition, Sony is also unifying the Alpha and NEX brands, so
all future interchangeable lens cameras will now fall under the
Alpha umbrella. Being mirrorless, the a7 would have otherwise
likely been prefixed with the letters NEX.
The a7 and a7R are identical in terms of physical design, with
the main differences being the sensor and autofocus system. The
a7 features a full-frame 24 megapixel CMOS, while the a7R has a
36 megapixel CMOS sensor with no optical low-pass filter. The a7
uses a Hybrid AF system (with on-chip phase detection) similar to
the one found on the NEX-6, while the a7R has traditional
contrast detection. The a7 is also capable of electronic first
curtain mode, which allows for a quieter shutter, and reduces the
potential for 'shutter shock' vibration; this is absent from the
A7R. Both cameras use Sony's latest Bionz X processor and also
have XGA electronic viewfinders, tilting LCDs, Wi-Fi, and
weatherproof bodies that resemble that of the Olympus E-M1.
As you'd expect, Sony had to come up with new lenses to take
advantage of the full-frame sensors, and they'll be known as
'FE-series'. Five lenses were announced to start with (listed
below), with ten more promised by 2015. Existing E- lenses
will work, though the image will (necessarily) be cropped. If you
have A- lenses laying around, those too will work, as long
as you pick up either of Sony's full-frame-ready adapters (the
LA-EA3 or LA-EA4).
Sony a7 key features
* 24.3 megapixel full-frame CMOS sensor with OLPF
* E- with support for FE, E, and A- lenses (with
adapter)
* Bionz X image processor
* Hybrid AF system with 25 contrast-detect and 117 phase-detect
points
* Weather-proof alloy and composite body
* Multi-Interface Shoe
* 3-inch tilting LCD with 1.23 million dots (640x480, RGBW) XGA
(1024x768) electronic viewfinder
* Diffraction correction technology
* Full HD video at 1080/60p and 24p; uncompressed HDMI
output
* Wi-Fi with NFC capability and downloadable apps
The a7 uses a 24.3 megapixel CMOS sensor with a low-pass filter
and on-chip phase detection. This 'Hybrid AF' is supposed to
result in speedier AF, supporting the camera's ability to shoot
at 5 fps with continuous autofocus. The more expensive a7R, on
the other hand, has a 36 megapixel sensor with no optical
low-pass filter and a more conventional contrast-detect AF
system.
Both the a7 and a7R can record video at 1080/60p and 24p, with
manual exposure control, headphone and mic ports, an audio meter,
zebra pattern, XLR support (via adapter), and live, uncompressed
HDMI output.
Bionz X Processor
The company's latest processor, dubbed Bionz X for reasons that
presumably made sense to someone, is considerably more powerful
than the previous generation, allowing what the company says is
more sophisticated processing.
Sony is being a little vague on specifics but is touting the new
processor as offering 'Detail Reproduction Technology' which
appears to be a more subtle and sophisticated sharpening system.
The company promises less apparent emphasis on edges, giving a
more convincing representation of fine detail'.
Another function promised by the Bionz X processor is
'Diffraction Reduction', in which the camera's processing
attempts to correct for the softness caused by diffraction as you
stop a lens' aperture down. This processing is presumably
aperture-dependent and sounds similar to an element of Fujifilm's
Lens Modulation Optimization system (introduced on the X100S),
suggesting it's something we should expect to see become more
common across brands in the coming months.
Finally, Sony says the Bionz X chip offers a more advanced
version of its context-sensitive, 'area-specific noise
reduction', which attempts to identify whether each area of an
image represents smooth tone, textured detail or subject edges
and apply different as of noise reduction accordingly. Later
in the review, we'll show you just how well this system works,
and also the problems it can create.
