The world-leading 24.6 megapixel Exmor CMOS sensor captures exceptionally fine detail like fine strands of hair, trees in a landscape and the texture of cloth.

The 900 sensor is as large as a 35mm film frame, meaning it can capture very fine detail that’s rich in colour, highlight and contrast. As a full frame sensor, it takes full advantage of the resolving power of the lens line-up without the image cropping issues associated with smaller sensors.

The 24.6MP sensor performs advanced processes such as analogue to digital conversion and Sony noise reduction that ‘cleans’ the signal output (both before and after conversion) to ensure crisp, sharp images even when shot at high ISO settings. And a 3-layer low pass filter preserves high resolution detail while suppressing moiré effects and colour artefacts.

The large sensor size also enriches your opportunities for creativity. The 900 takes high ISO shots with less noise, so you can shoot at much lower ISOs than previously, opening up a whole new world of available light shooting.

The 3” Xtra Fine LCD screen of the α900 provides exceptionally high resolution image reproduction enhanced by an anti-reflective coating.

If the 270 ppi screen resolution was any higher, the human eye would be incapable of distinguishing the difference. That equates to around 920,000 dots of ultra-sharp image display for precise on-the-spot review plus the capacity to zoom in on detail to confirm focus.

The LCD screen displays detailed shooting information and at the touch of a button, the Quick Navi menu for easy adjustment of shooting parameters. The screen automatically switches to a vertical-format when you turn the camera sideways; and to conserve battery power, switches off altogether when you put your eye to the viewfinder.
Then when reviewing your images, histograms provide on-the-spot confirmation of exposure balance and highlight/shadow reproduction.

The 900 also features a handy top-mounted LCD for at-a-glance confirmation of settings like battery level, frames remaining, drive mode, shutter speed, aperture and exposure compensation.

Exclusive to Sony, the Dual BIONZ image processor sits at the heart of the 900; processing the wealth of visual information flowing through the lens to perfectly replicate colours, texture and depth.

900 captures a vast amount of information. So a dual processor has been incorporated to convert this mass of data into stunning images.

The advanced Dual BIONZ system processes at lightning speed, providing quick shooting response and totally natural colour and tonal gradation. At the same time, noise is suppressed both before and after RAW data conversion, so detail, colour and contrast are perfectly captured every time.

This powerful processor also provides more creative options, reflecting the desired settings and Creative Styles you’ve selected and allowing you to further customise styles to your own individual preference.

The 900 features the world’s first 35mm full frame sensor image stabilisation system to neutralise the effects of camera shake, regardless of the lens you are shooting with.

The slightest movement can spoil a beautifully constructed shot. So the 900 incorporates SteadyShot INSIDE to keep images as sharp as possible.

Some anti-shake systems are lens-based so to benefit from the technology, you are restricted to certain lenses. But Super SteadyShot INSIDE is actually built into the 900 body, shifting the full frame image sensor to compensate for camera shake in real time. So blur is reduced whatever lens you are using, even if it’s a macro or wide-angle one.

SteadyShot INSIDE is faster and more powerful than previous systems, allowing you to shoot 35mm full frame images at shutter speeds from 2.5 to 4 steps slower than would otherwise be possible. So even shots that would normally require the use of a tripod or flash can now be taken handheld.

The D-Range (Dynamic Range) Optimiser works with the 900 full frame sensor to provide better balance to images shot with extremes of light and shadow.

High-contrast or strongly backlit scenes can lead to loss of highlight and shadow detail and tonal gradations.

While normal exposure compensation maintains low-light detail at the expense of burnt out highlights, the D-Range Optimiser gives you perfectly exposed photographs. It does this by automatically adjusting the exposure levels for the whole scene.

The 900 also features an Advanced Mode, which offers a higher degree of compensation by analysing and adjusting each tonal area of the image separately. Bracketing functions also record the image at different optimisation levels for easy ‘best shot’ selection.

The combination of an anti-static coating and high-speed sensor vibration on turn-off, keeps your images dust free every time

All 900 buttons, dials and switches are protected from dust and moisture using gaskets and sealants. But what about dust particles contaminating the sensor when you’re changing lenses?

A Dual Anti-Dust System is employed in the 900 to reduce the risk of blurry marks spoiling your photographs.

The first component is an anti-static coating that repels dust, making it easier to remove particles from inside the camera with a blower.

The second component is a high-speed sensor vibrator that shakes off any particles each time the camera is switched off.

The optically-precise α900 viewfinder provides brilliant image previews covering virtually 100% of the area of the 35mm full frame 24.6MP sensor.

It combines a high-quality optical glass pentaprism with a new high-power condenser lens to deliver brightness and 0.74x magnification.

Distortion is practically eliminated while multi-layer anti-reflective coatings help prevent ghosting. A spherical acute matte focusing screen aids manual focusing, and alternative specifications are available as options, to match your personal preferences.

The  900 viewfinder also incorporates its own shutter to stop extraneous light affecting the settings when taking long exposure shots like night skies or fireworks.

A wide range of lens options including a Sony-exclusive suite from Carl Zeiss, gives the α900 enormous potential for creativity.

Even the most demanding creative photographer will now be satisfied by this expanded range of -compatible lenses.

From 11mm wide angle to 500mm reflex; with fixed, zoom and specialist options in between; all possible shooting scenarios are covered.

The body, chassis and interface of the 900 incorporate design features that meet the highest standards, even in the worst operating conditions.

The designers of the 900 utilised techniques and materials used in the manufacture of the rugged broadcast-quality video cameras produced by Sony. These include the strong and lightweight magnesium alloy body which protects the 900 against the rigours of an active life; and O rings that seal the operating interface, keeping out dust and moisture.

Then within the camera, the combination of a high tensile-strength aluminium alloy chassis and high-rigidity engineering-grade plastics provides additional structural integrity with low weight.

The shutter unit is the hardest-working moving part in any DSLR. The 900 unit is built to handle 100,000 shutter release cycles between services, withstanding exceptional shooting demands like 1/8000 second shutter speeds and 5 frames per second continuous shooting.
