Sony is expanding its Alpha digital
SLR system with the introduction of the DSLR-A700 camera, which is aimed at
photo enthusiasts or serious photo hobbyists.
The new model features advanced imaging technologies and
ultra-responsive operation, as well as a lightweight, dust- and
moisture-resistant, magnesium alloy construction common to enthusiast-class
D-SLR cameras.
Like Sony's mainstream DSLR-A100 model, the new A700 unit incorporates
Super SteadyShot(R) Inside image stabilization in the camera body and is
compatible with most Minolta Maxxum(R) mount lenses in addition to Sony
lenses.
"Discerning photo enthusiasts will be impressed with the rugged
construction and outstanding performance of the A700," said Phil Lubell,
director of marketing for digital cameras at Sony Electronics. "We also
expect that this new camera will re-define the post-capture experience with
HDMI(TM) output for high-quality playback of images on high-definition
televisions."
Picture Quality
The camera's new 12.2-megapixel Exmor(TM) CMOS sensor conducts
analog-to-digital (A/D) signal conversion and dual noise reduction right on
the sensor itself. Noise reduction is applied to analog signals before A/D
conversion and the resulting digital signals are then subject to a second
round of noise reduction.
According to Lubell, "These digital signals are virtually immune to
external noise and interference."
Clean, noise-free digital signals are then sent to the newly developed
BIONZ(TM) processing engine. Lubell said this engine has been optimized to
process data-rich picture information at high speeds, and to reduce picture
noise in the RAW data stage before final image compression and encoding.
The results are high-resolution, detailed images with rich tonal
reproduction.
Extraordinary Responsiveness
The A700 camera is engineered to be fast and ultra-responsive so as to
become "a virtual extension of your own senses," Lubell said, "capturing
fleeting moments as you see them."
A newly developed, auto-focus system features 11 wide-area sensors,
including a center dual cross sensor comprised of two horizontal and two
vertical line sensors for exceptional AF precision. An F2.8 line sensor
leverages the brightness of fast aperture lenses for even greater
precision. Lubell said that extraordinary focusing speed has been realized
through improved algorithms and a high-torque focusing drive motor.
The large, bright, viewfinder uses a precision-ground optical glass
pentaprism and a high refractive index eyepiece lens to provide 0.9x
viewfinder magnification and 95 percent frame coverage. Manual focusing is
aided by an interchangeable spherical acute matte focusing screen.
The camera has a high-performance vertical traverse shutter with a
maximum shutter speed of 1/8,000th of a second to freeze fast-moving
action. A high-power coreless motor charges the shutter and mirror
mechanism, allowing continuous shooting at up to five frames per second. In
JPEG fine or standard
mode, continuous shooting is limited only by the capacity of the media
card (sold separately), while up to 18 frames can be captured in RAW.
The new camera features fourteen creative styles, including night view,
autumn leaves or vivid, which can be selected to enhance images. These
effects can then be fine-tuned by customizing contrast, sharpness, zone
matching and other parameters.
Sony's Dynamic Range Optimizer (DRO) function has been updated on this
model so users can choose the desired level of detail recovered in areas of
shadow. The advanced mode offers the option of five levels of user
selectable correction. Additionally, DRO bracketing creates three images
from a single capture with three different levels of DRO.
There is an extensive array of customization options to personalize the
camera to match shooting styles. The unit's quick navigation interface can
be accessed instantly with the four-way multi-selector, and selected
parameters can be adjusted directly by control dials.
Up to 28 camera settings can be stored in one of three user memories
for instant recall. The unit's custom function button can be assigned to 15
frequently-accessed functions.
DSLR-A700 Camera
With the supplied remote capture application, the camera can be
controlled from a compatible PC via USB without even touching the camera,
and files can be stored on the computer instead of the media card.
High-Quality Pictures on an HDTV
The A700 model features an HDMI output for connection to HDTV sets,
putting a high-resolution spin on the conventional photo slideshow. When
connected to a Sony BRAVIA(R) LCD HD television, photos are optimized for
viewing with the new "PhotoTV HD" mode. This mode brings the look of actual
printed photography to the television, reproducing high-quality digital
photos by fine-tuning such image parameters as sharpness, gradation and
color specifically for photographs.
The exceptional viewing experience of this camera also extends to
viewing photos on its 3-inch LCD screen. The screen's size and ultra-sharp
resolution (921K) makes it possible to check focus and image quality with
much greater accuracy.
A Flexible System
The camera will be introduced with two new lenses, bringing Sony's lens
and teleconverter catalog up to 23 models. Supplied as a standard kit lens,
the new DT 16-105 mm f.3.5 - 5.6 lens features a distinctive zoom range
(35mm equivalency of 24 - 157.5 mm); compact, lightweight design; and
internal focusing. The other addition is a powerful and compact
high-magnification DT 18 - 250 mm f3.5 - 6.3 lens. Sony is also planning to
introduce a specialty 70 -300 mm f4.5 - 5.6 SSM G telephoto lens featuring
super sonic wave motor auto focus drive system for smooth auto focusing in
Spring 2008.
Sony's full line of accessories will also expand to include a new
vertical grip. Equipped with buttons and switches for the most essential
control functions, it offers the same ease of operation and handling as
when shooting vertically. It houses two InfoLithium(R) batteries (sold
separately), which will automatically switch to the second battery when the
first one runs out. Remaining charges of both batteries are displayed on
the camera's LCD screen.
Memory That Keeps Up With The Camera
The model also features separate slots for Memory Stick Duo(TM) media
cards compatible with the Memory Stick PRO-HG(TM) high-speed data transfer
standard, as well as CompactFlash(TM) Type I/II media cards compatible with
the new Ultra Direct Memory Access standard for up to 300x write speeds.
Sony is also introducing new 300x high-speed CompactFlash(TM) memory cards,
ideal for high-end photographers requiring fast write speeds. The ne
models, available in 2GB or 8GB capacity, expand Sony's current line of
CompactFlash cards that also include 66X and 133X speeds, with capacities
ranging from 1GB to 4GB.
The DSLR-A700 camera body, DT 16 - 105 mm lens, and DT 18-250 mm lens
will be available for about $1,400, $580 and $550, respectively. The
DSLR-A700K kit with an 18-70 mm lens will be available for about $1,500,
and the DSLR-A700P kit with the 16-105 mm lens will be available for about
$1,900. The camera body and DSLR-A700K kit will ship in October and the
DSLR-A700P kit in November.
