Conclusion: The Alpha 900 represents in a nutshell the almost schizophrenic nature of Sony's digital camera division, which can market compact cameras with smile detection and a Playstation style user interface at the same time as this, perhaps the most pared-down, frill-free and unashamedly 'serious' DSLR we've seen in a long time.
Pros: Class-leading resolutionv (as long as your lenses are good enough), incredibly solid build quality, environmental sealing, Intuitive operation and uncluttered control and menu system, Excellent out of camera JPEG results with superb tonality, dynamic range, color, Excellent raw dynamic range gives lots of headroom, Almost 100% reliable metering and exposure, Very fast and responsive body - remarkable burst mode (5fps RAW+JPEG, 24.6 MP), In-body image stabilization tha...
Cons: Noise reduction settings applied to raw as well as JPEG files - cannot be 'turned off for raw but left on for JPEGs' (as is normal practice), Relatively high levels of noise at anything over ISO 400 (ISO 6400 is of very, very limited use), Destructive noise reduction on high ISO JPEGs removes too much detail, JPEGs a little soft by default (some loss of detail due to NR visible even at ISO 200) - you really need to shoot raw (and use ACR or similar) to get the best ou...
Conclusion: Sony Alpha DSLR cameras Sony showed the world that it is possible to bring out an entire line-up of digital SLR cameras in a short period of time and at an immense speed. And not only that, it puts Sony ahead of the competition with certain techniques that the rivals aren't yet using. Sony takes over the lead from Canon as we solely look at the amount of Megapixels, which will be good from a marketing viewpoint.
Summary: Sony’s Alpha DSLR-A900 feels like it’s been with us for a long time – after all, the prototype was first shown back in March 2007 and its sensor unveiled in January 2008. So unlike its rivals which are often sprung with little notice, we’ve long-known what Sony’s flagship DSLR would look like and speculated how its new 24 Megapixel full-frame sensor may perform in practice.
Pros: Technically highest resolution to date., Built-in image stabilisation., Superb viewfinder with 100% coverage., Quick handling and 5fps shooting.
Cons: More noise than rivals above 400 ISO., No Live View or movie function., Upper information screen very basic., Tendency to underexpose in our tests.
Sony brings more megapixels to the table, serving up one of the most delicious full-frame D-SLR cameras on the market.

Summary: Anyone looking to make the step up to a full-frame D-SLR should make a point of trying out the Sony A900. It's a great camera to use and its performance on location and in the studio was excellent.
Pros: Comfortable to use, manual controls for metering and focus modes, fast, full-frame sensor, huge resolution
Summary: The Sony A900 is not simply the highest-resolution DSLR out there – it's much more than that. If you've read through the
Ease of Use
sections of this review, you will know that I liked working with this camera a lot. Its viewfinder is the best you'll find south of medium format, the build is incredibly robust, the controls are intuitive, with some of them – such as the dedicated Histogram button, the metering mode knob or the well-implemented rear...
Excerpt: Sony claim to have cemented their place in the digital SLR market with the Alpha 900 and while they’ve got a long way to go before they take any serious stranglehold on the monopoly that in reality belongs to Canon and Nikon, it is fair to say that Sony have finally arrived with some serious ammunition on the back of the A900. First thing to note is the whopping 24.6-megapixels combined with a full...
Summary: The A900 is a bold first step for Sony in different ways. It's their first full frame camera and is their first semi-pro model. Buying Minolta's camera division was a good idea as they've gained decades of SLR experience as well as a lens mount that is well established. Couple that with a collaboration with the greatest lens maker in the world and Sony are looking prettier everyday.
Pros: Bright viewfinder and mirror, Full frame, Camera based IS, Good noise control, Preshot preview, Good colour rendition, Backwards compatability, Weather sealing, Remote trigger software
Cons: Portraits under exposed slightly, Joystick could cause problems later, Intelligent preview has no focus control
