Sony A900 Full Frame DSLR -Sony is introducing its full-frame α (alpha) DSLR-A900 camera,
aimed at serious photo enthusiasts looking for traditional SLR performance with
the added benefits of digital photography.
It is designed to deliver ultra-fine picture quality with the world’s highest
resolution, 24.6-megapixel, 35 mm full-frame CMOS sensor and fast image
processing with a new dual BIONZ® processing engines. The camera is also the
first to have a body-integrated image stabilization system for a full-frame sensor
with Sony’s SteadyShot® Inside anti-shake system.
One look at the camera’s distinctive pentaprism and nostalgic body design will
evoke its full-frame optical performance. It features a bright, clear optical
viewfinder with 100% field of view coverage that would impress even film
photography loyalists.
“The α (alpha) DSLR-A900 introduction solidifies Sony’s position as a leading
camera manufacturer that can meet the demands of serious enthusiasts,” said
Phil Lubell, director of digital camera marketing at Sony Electronics. “It
represents the best in sensor and image processing technologies and offers
enhanced functions, performance and reliability so photographers can push their
creativity to the limit.”
Ultra-Fine Images As The Human Eye Perceives
Them
The camera’s Exmor™ CMOS sensor delivers the photographic expressive power of
wide angles and perspective that only a 35 mm full-frame sensor can offer, and
is designed to take advantage of the resolving power of high-precision α
(alpha) lenses. Its high pixel count and large size provide enhanced image
detail and a wider dynamic range for natural color reproduction and subtle
tonal gradations.
The sensor is produced using proprietary Sony planarization technologies to
ensure an ultra-flat surface across the entire imaging area. Instead of a
single analog/digital convertor, the sensor uses over 6,000 on-chip,
column-parallel A/D converters to convert analog signals to noise-resistant
digital signals at the earliest possible stage. The result is reduced noise and
high-speed transfer of data.
Image processing gets a boost in speed and power from the application of two
BIONZ image processing engines. Large amounts of data captured by the
24.6-megapixel sensor can be quickly processed to achieve a fast shooting
response. Additionally, this dual BIONZ processing system applies advanced
noise reduction algorithms producing images of exceptional quality and detail,
especially at high ISO sensitivities.
World’s First Anti-Shake System for a
Full-Frame Sensor
The camera’s newly-developed, body-integrated SteadyShot Inside unit achieves
an anti-shake effect equivalent to shutter speeds faster by 2.5 to 4 stops.
This new unit provides stabilization for Sony, Minolta and Konica-Minolta wide
angle, large-aperture lenses, which is difficult for lens-integrated systems.
State-of-the Art Optical Performance and
Responsiveness
The ultra-bright viewfinder with 100% field of view coverage and 0.74x
magnification enables accurate framing and preview. It features a high-power
condenser lens, an eyepiece with high reflective-index glass, and a
multi-layer, anti-reflective coating on every optical surface to deliver its
extraordinarily bright and accurate view.
Additionally, the focusing screen is user-replaceable, with additional L-type
(grid pattern) and M-type (super spherical acute matte) screens sold
separately.
The camera’s newly-developed autofocus system consists of nine wide-area
sensors with 10 assist points for improved tracking of moving subjects. A
center dual cross sensor comprised of two horizontal and two vertical line
sensors as well as a dedicated f/2.8 sensor are included to achieve greater
precision, especially when using fast-aperture lenses.
It also offers high-speed continuous shooting of 24.6 megapixel images at five
frames per second. A newly-designed mirror box features a unique parallel-link
mirror mechanism that moves on two horizontal axes to accommodate both 100%
viewfinder coverage and the body-integrated image stabilization system without increasing
the camera’s size. The mirror box also has a new moving magnet actuator, a
high-powered coreless motor for a faster shutter charge, and a magnet catcher
to minimize mirror bounce and light refraction within the box.
Versatility to Unleash Creative Possibilities
The model’s innovative intelligent preview function takes the guesswork out of
setting up a shot and the hassle of taking multiple shots to achieve a desired
effect.
After pressing the depth of field preview button, the camera “grabs” a RAW
preview image which is processed and displayed on the LCD screen. You can then
fine tune white balance, determine the best level and effect of dynamic range
optimization, adjust exposure compensation and check histogram data, all before
you actually take the picture. Preview images are not recorded on the camera’s
memory card, thus saving capacity.
Other key features aimed to expand creative options include the Dynamic Range
Optimizer (DRO) with five levels of user-selectable correction as well as DRO
bracketing for enhanced scene analysis and graduation optimization. EV
bracketing with ±2EV range makes it easy to create high dynamic range composite
images.
Thirteen creative styles can be selected to enhance images and then fine-tuned
by customizing contrast, sharpness, zone matching and other parameters, while 3
user-programmable memories provide instant access to as many as 26 different
mode settings.
Powerful RAW file processing control is put in the photographer’s hands with
the included Image Data Converter SR3 software that delivers faster file
processing speeds, easy adjustment of image parameters, Dynamic Range
Optimization and a new Peripheral Illumination function that compensates for
corner light fall off.
With the camera’s HDMI output and Photo TV HD mode, your creative output can be
enjoyed on a compatible HD television. This mode brings the look of actual
printed photography to the television, by fine-tuning such image parameters as
sharpness, gradation and color.
Comfort in Your Hands
Its construction features rugged, lightweight magnesium alloy with
moisture-resistant, rubber seals for buttons and dials, an anti-static coating
to prevent dust adherence to the imager, and a high-endurance shutter rated for
more than 100,000 release cycles.
It has a 3-inch, Xtra Fine LCD screen (921K) makes it possible to check focus
and image quality with accuracy. It incorporates an easy-to-see display with a
quick navigation menu to easily access common functions without interrupting
your creative flow. A backlit LCD panel sits on top of the camera and displays
key settings.
System Expansion with New Accessories
The A900 camera will be accompanied with an array of accessories like the
recently-announced Sony HVL-F58AM flash unit with its innovative Quick Shift
Bounce system, powerful performance with a guide number of 58, and wireless
auto flash ratio control.
The Sony® VG-C90AM vertical grip offers the same ease of operation when
shooting vertically as horizontally, with its button layout and low-position
shutter-release button. It also houses two InfoLITHIUM® batteries (sold
separately) for longer shooting and playback.
The DSLR-A900 body will be available in November for about $3,000 along with
related accessories.
