SAN DIEGO –
Sony unveiled a pair of new NEX-series
compact interchangeable-lens cameras and a pair of
Alpha series d-SLRs for advanced photo enthusiasts.
The company also announced a second-generation
model of its consumer-level interchangeable-lens camcorders
– the NEX-VG20 (shipping in November at a
$1,599 suggested retail), which takes E-mount lenses
designed for the NEX camera family.
The new Alpha d-SLRs include the A65
and A77 models, both of which incorporate
Sony’s unique Translucent
Mirror technology and are
scheduled to see fall market
The translucent mirror technology,
which was introduced
last year, allows the camera to
continuously track and adjust
exposure and focus through to
image capture. Other d-SLRs lose
the ability to continuously adjust
focus and exposure after the reflex
mirror is raised prior to exposure.
The camera also includes an
electronic first curtain technology
that significantly reduces release
lag time and lets the camera go
directly from live view to an exposure without cycling the
focal plane shutter.
The A77, which is the successor to the popular A70,
is scheduled to fit in the $1,200 to $2,000 price point
class when it ships in October. Amazon is showing
the body only at a $1,400 price point. It features a fulltime
continuous AF system with tracking focus at high
speed, and phase detect AF in movie mode.
It includes a new 19-point AF system with 11 cross
sensors and enables high-speed shooting in up to 12
fps with full resolution.
The camera includes an ultra-high resolution
24.3-megapixel APS-C Exmor R CMOS image sensor,
Bionz image processor and records video in up to
FullHD 1080/60p and 24p format with improved sound.
As with several Alpha models introduced last year, the
A77 includes an electronic viewfinder, but is one of the
first cameras to use OLED (2.5 million dots) technology
in a eye-level viewfinder instead of LCD. Sony calls
the feature an XGA OLED Tru-Finder.
The company also employs a three-way
tiltable LCD and includes built-in image
Low-light shooting is supported with
an ultra-high ISO range from 100 to
16,000. Also included is a built-in flash,
extensive weather sealing throughout the
camera, multi-frame A-HDR capability
and a cropped zoom (12-megapixel, 1.4x
crop factor) function.
The Alpha A65 d-SLR, which will ship in
October at $899 (body only) or $999
(with 18-55mm lens) is positioned at the
top of the entry d-SLR class, Sony said.
It features the same 24.3-megapixel Exmor
R CMOS imager as the in the A77,
but steps down to 10 fps shooting with
continuous AF and object tracking.
The AF system steps down to 15 sensor points with
three cross sensors.
It also uses a new Bionz processor, includes an
electronic first curtain feature and captures video in
1080/60p in AVCHD Progressive compression format.
The A65 also features an eye-level 921,000-dot
OLED EVF, articulating LCD screen, full-time continuous
AF, ISO range from 100 to 16,000 and built-in image
Both the A65 and A77 also include Sweep Panorama
and 3D Sweep Panorama functions, GPS geo-tagging
capability and D-Range optimization.
Sony’s new additions to the NEX-series compact mirrorless
interchangeable-lens cameras include the NEX
5N and NEX 7 models, to fill out a three-model lineup
The NEX 5 is expected to ship in September at a
$600 suggested retail for the body only or $700 with an
18-55mm lens. The NEX 7 is expected in November at
a $1,200 suggested retail for the body or $1,350 with
an 18-55mm lens.
The NEX 5N, which is the successor to the NEX 5,
features a 16.1-megapixel APS-C EXMOR R CMOS
image sensor, new Bionz image processing, electronic
first curtain technology for a release lag time
of 20ms (.02 seconds) and up to 10fps continuous
The new NEX-7 camera will feature a built-in eye level
OLED EVF, a new 24.3-megapixel APS-C image sensor,
new Bionz image processor, and a new Tri-Navi
three-dial control (two on top one on the back) interface
for very detailed control.
