Summary: The Sony Alpha A100 is a superb and well valued DSLR camera. This 10 megapixel digital SLR is packed with useful features and technology such as body-based stabilization and a hardware dust-reduction system. With body-based stabilization, all lenses automatically benefit from stabilization, even ultra-wide-angle lenses, at no additional cost.
Pros: Superb photo quality, Great color accuracy, Very good dynamic range, Excellent metering and exposure, Low image noise up to ISO 400, Effectively stabilizes all lenses, Hardware dust-reduction, Very fast and responsive, Fast focusing, Good ergonomics, Eye-start auto-focus, Excellent build quality, Selectable low-key and high-key tone-curve, Ambient and flash-based exposure compensation, Good battery life
Cons: Quite noisy and low-saturation at ISO 1600, Slightly above average noise at ISO 800 for a DSLR, Long exposure noise-reduction image artifacts, Dynamic range optimizer not reliable, Rare multi-segment exposure errors
Excerpt: It’s a good-sized dSLR camer a with a sturdy plastic shell over a metal frame. The camera is easy to hold, with a substantial right hand grip, and the important controls are within easy reach of your fingers. The A100 has quite a few buttons and dials, which can be intimidating to new users.
Excerpt: For its first digital SLR, Sony took the best of what it inherited from its acquisition of Konica Minolta and added some new features that have made its competitors sit up and take notice. From the "something borrowed" category, the Sony A100 sports an in-camera image stabilization system called Super SteadyShot, which is based on Konica Minolta's tried-and-true sensor-shifting technology.
Conclusion: Sony's entrance to the digital SLR market comes thanks to their finial association with and later purchase of Konica Minolta's photo division. When you first use the A100 it clearly has more Konica Minolta DNA than Sony however their influence comes in the added features and image processing (the camera's user interface and control systems are very similar to previous Konica Minolta digital SLR's, and that's no bad thing).
Pros: Excellent resolution, plenty of detail although no leap over eight megapixels, Vibrant color response, similar hues to other digital SLR's, About a third of a stop more sensitive than indicated, Neutral tone response with soft roll-off in highlights, In-body SteadyShot system provides about 2 stops of additional shutter speed latitude, All your lenses become 'SteadyShot' at no extra cost, Extra highlight detail using the High Key Hi200 setting, In-hardware Dynamic Ran...
Cons: High sensitivity noise at ISO 800 and 1600, Occasional Multi-segment metering under-exposure, Long exposure noise reduction artifacts (black pitting, softness, posterization), Limited image parameter adjustment (only -2 to +2), LCD anti-reflective coating becomes smeared with marks easily, Proprietary hot-shoe design (fewer third party flash / accessories), Flash must be raised for AF assist, Unable to control in-camera high ISO noise reduction, Blinking highlights on...
Conclusion: The Sony A100 is competitive in performance with the cheapest Canon and Nikon bodies. The Sony system of lenses and accessories is smaller than Pentax's and much smaller than Canon's and Nikon's. The A100's main advantage over similar priced bodies from Canon and Nikon is the built-in image stabilization. The A100's main weakness is objectionable noise at higher ISO settings.
Conclusion: Sony Alpha 100 digital reflex camera No one will be surprised that Sony's first digital SLR camera bears a strong resemblance to one of Konica Minolta's models. Sony took over the camera division of the illustrious brand and the two companies had been working together even before the takeover. However, Sony has done more than just put a simple clone on the market: certain things have been added and changed. Generally, they have been to the benefit of the camera.
Excerpt: Sony finally landed in the dSLR market with Alpha dSLR-A100 after collaboration with Konica Minolta last year. The later has now quit the scene and passed on the proven digital SLR technologies to Sony - most notably being the lens mount and anti-shake system. The Sony Alpha DSLR -A100, in short, the A100, is a 10.2 Megapixel, 3 frames per second SLR based on the MAXXUM 5D (a Konica Minolta dSLR) with a high resolution LCD display.
Excerpt: Sony has always been a leading force in technology. They were the first to produce a prototype of a digital camera when other companies were still contemplating the idea. Sony used the body of the Konica Minolta to produce this camera. Perhaps it does not look like a Sony camera because it is lacking the Sony symbol which can be confusing to some consumers.
Summary: It’s always exciting to see the very first camera from a new (to this market) company. Sony’s reputation in consumer electronics whipped up a lot of hype in this camera, some of which is deserved, but generally overblown.
Pros: Image stabilisation, promising range of lenses, pleasant images, good LCD, good image noise control, high resolution, button placements
Cons: Shutter noise, slight oversaturation of images, no histogram, extended dynamic range less effective than hoped, average build quality
Sony Alpha DSLR-A100 review with DT 18-70mm f3.5~5.6
1 July 2006
Summary: But it's not all good news. Increasing resolutions on sensors with the same
surface area always raises concerns over higher noise levels, and as our
, the A100 is noticeably noisier
than rivals like Canon's EOS-350D / Rebel XT, particularly at 800 ISO and above.
Our gallery also reveals higher noise levels than we'd like even at 400 ISO.
Pros: Unique and effective built-in anti-shake system, High resolution 10 Megapixel sensor, 18-70mm kit lens longer than the usual 55mm, Screen information stays upright as body rotated
Cons: Anti-dust system far from infallible, Relatively noisy at 800 ISO and above, Kit lens soft in corners when open at wide angle, Can't see effect of anti-shake while composing, Feels like an enhancement, not a new DSLR
