SONY ALPHA DSLR-A900


Sony Alpha DSLR-A900
With the Alpha A900 featuring a full 35mm frame-sized image sensor, Sony has joined a rather exclusive club of Full Frame DSLR. To date only four companies have offered full-frame digital SLRs. Among these, two - Contax and Kodak - have since left the digital SLR market altogether. That leaves Sony in a head-to-head battle with the two giants of the photographic industry - Canon and Nikon. Each rival offers two full-frame digital SLRs. Sony has loaded some new features so if you are making up your mind to buy a full frame SLR then don’t forget to give a serious look on the special features of this camera.


The Sony Alpha A900 has a whopping 24.6-megapixel resolution from its full-frame Exmor CMOS image sensor -- the highest sensor resolution of any 35mm digital SLR yet announced. Extraordinary resolution, nothing touches it at its price point .
It has got built-in SteadyShot image stabilization .Now no need to expend more on VR OR IS lenses. All your old normal lenses work as Images Stablised.The sensor is mounted on a moving platter that allows for in-camera image stabilization, branded as SteadyShot Inside. That's another world's first for a full-frame digital SLR, and it gives as good for a 2.5 to 4-stop improvement during hand held shooting. Rear panel of the camera features a large 3-inch LCD display with 921,600 dot resolution, equating to VGA (640 x 480) pixel with three R, G and B dots per pixel. The Sony Alpha A900 offers ISO sensitivity from 200 to 3,200 equivalent, but is expandable to ISO 100 to 6,400 equivalent. Shutter speeds range from 30 to 1/8000 second, plus a bulb setting, and x-sync is 1/250 second (or 1/200 second when SteadyShot is enabled).
The camera has got an Intelligent Preview feature is a real time-saver for determining best camera settings.The camera comes with user interchangeable focusing screens. It is also lighter than the only other full-frame in its resolution class (Canon EOS-1Ds Mark III). The only thing I missed was the live view. Below some of its features are given in full detail as per Sony Global site (http://www.sony.net/ enjoy……………………

24.6-megapixel Exmor™ CMOS 35mm full-frame imaging

The α900's image sensor is designed from the ground up for 35mm full-frame imaging, and is produced using proprietary Sony planarization technologies to ensure an ultra-flat surface across the entire imaging area. Instead of a single analog/digital converter, the sensor uses over 6000 on-chip column-parallel analog/digital converters to convert analog signals to noise-resistant digital signals at the earliest possible stage. In addition, noise reduction is applied both before and after analog/digital conversion to ensure cleaner signal output. The result is not only higher image quality, but also blazingly fast sensor response

Dual BIONZ™ image processing for truly lifelike and natural color
Image processing gets a big boost in speed and power from new dual BIONZ image processing engines on the α900. As a result, even the massive amount of image data captured by the 24.6-megapixel Exmor CMOS sensor can be processed instantly, assuring you of quick shooting response and truly natural, what-you-see-is-what-you-get color and tonal gradation. In addition, the dual BIONZ engines apply advanced noise reduction algorithms twice — once prior to RAW data conversion and again during image processing — to ensure an absolute minimum of noise in final image data.
Faster, more powerful SteadyShot® INSIDE
To match the larger size and higher image quality specifications of the new 35mm full-frame Exmor CMOS sensor, the α900 features a SteadyShot INSIDE image stabilization system that is 1.5x more powerful, and 1.3x faster, than previous systems. Enabling you to enjoy handheld shooting at shutter speeds up to 4 steps slower than would otherwise be possible,* the body-mounted SteadyShot INSIDE system works with all compatible α system lenses — including macro and wide-angle lenses — and doesn't cause the image degradation that can occur with lens-based optical stabilization systems.
Unparalleled viewfinder brightness and a 100% field of view (approx.)
The α900's viewfinder is a masterpiece of optical precision in its own right. Featuring a high-quality optical glass pentaprism and a new high-power condenser lens, it offers truly exceptional brightness, 0.74x magnification (approx.) and a field of view that covers virtually 100% of the 35mm full-frame sensor's large imaging area. A high refractive index glass eyepiece and condenser lenses virtually eliminate distortion, while multi-layer anti-reflective coatings help prevent ghosting. A spherical acute matte focusing screen aids manual focusing by making it easy to identify correct focus, and a high eyepoint improves visibility when wearing eyeglasses
Optional focusing screens to suit your shooting style
According to your preference or shooting needs, the standard Type G spherical acute matte focusing screen that comes with the α900 can be replaced with an optional Type L spherical acute matte screen or Type M super spherical acute matte screen. The L type features grid lines to enable easier framing, while the M type is particularly well-suited to bright lenses with an aperture of F2.8 or greater, and features a high-dispersion screen that makes it easier to fine-tune the focus manually
Dust and moisture protection for worry-free outdoor shooting
To allow worry-free shooting in adverse environmental conditions,* the α900's controls, terminals, viewfinder, and other sensitive components are protected from dust and moisture by rubber seals.
D-Range Optimizer for rich tone gradations in high-contrast light
When photographing scenes that contain extremes of light and shadow, it can be difficult to capture the full range of tonal gradations that the human eye can see. But with the α900's D-Range Optimizer function, the camera analyzes the scene for you, and automatically adjusts gradation reproduction parameters to assure optimum exposure balance, with richer highlight and shadow detail.In Standard mode, the D-Range Optimizer analyzes the overall image before performing the optimization, and in Advanced mode,* it analyzes each area of the composition separately. On the α900, improved algorithms assure even better performance, with a choice of Advanced Auto and Advanced Level settings you can use to help you capture the level of highlight and shadow detail you want. In addition, there's a D-Range Optimizer bracketing function that records images at three different optimization levels to allow best-shot selection.
Preview function for exposure effect simulation
Another advanced function introduced for the first time on the α900 is Intelligent Preview. Using this function, you can simulate the effect of various D-Range Optimizer, exposure compensation, and white balance settings, and display the result on the LCD monitor without actually taking a picture. It's a great way to fine-tune image adjustments in advance when working with a tripod and complex shooting setup.
3-inch* Xtra Fine LCD monitor for sharp, clear image review in any light
On-the-spot image review is easy thanks to a 3.0" Xtra Fine LCD monitor with a screen resolution of 270 ppi (approx.), which is even higher than the 220 ppi resolution generally considered to be the upper limit of what the human eye can perceive. Hybrid construction and an anti-reflective coating improve monitor visibility when shooting outdoors, and there are a wide choice of index view options to facilitate best-shot selection, as well as a full-featured RGB histogram and shooting information display.
Micro Adjustment for lens-specific focus tuning
With AF Micro Adjustment switched on, you can fine-tune the AF focus point for up to 30 different lenses in +/-20-step increments. Adjustments can then be stored in the camera's memory and will be automatically applied when the same lens is mounted again.
Turn your Sony BRAVIA™ HDTV into a personal digital art gallery
For the ultimate experience in home viewing pleasure, simply connect the α900 directly to a Sony BRAVIA HDTV ? the TV will automatically switch to PhotoTV HD mode, enabling you to enjoy and share your photos in a dramatic new way. It's a totally new viewing experience, one that combines the transparent clarity, color fidelity, and rich contrast of positive film with the big-screen impact of a slide projector.From breathtaking scenic photos and landscapes to photos of your family and friends, BRAVIA PhotoTV HD brings out radiant beauty in every detail, filling the room with luminous, high-resolution images that launch photography into a new dimension. It's like having a digital art gallery right in your own living room.
Remote Camera Control for remote recording and control
Improved Remote Camera Control software expands your shooting horizons by enabling you to capture images remotely and record them directly on your computer's hard disk. A new interval recording function* has also been added to the program's impressive feature set, which includes virtually all basic camera controls, as well as white balance, image quality, and D-Range Optimizer settings
