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
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...
Excerpt: Sony has finally entered the digital SLR game with its new 10MP Alpha 100, and it's full of surprises. Does this newcomer stand a chance against veteran DSLR players Canon, Nikon, Olympus, and Pentax? Some might have said, "No way!" before Sony acquired Konica Minolta's DSLR division earlier this year. But now, by combining some of KM's best DSLR features with Sony's advanced sensor technology and design innovations, the Alpha 100 makes it a whole new game.
Excerpt: We used to have a lot of questions about Sony's takeover of Konica Minolta's camera division. Now, after running a full set of Certified Lab Tests and field tests of the new 10.2MP Sony Alpha 100 ($900, street, body only), only one question is left: How will Sony make enough of them to satisfy the demand for a camera that outperforms anything in its price range?
Excerpt: Most photographers shooting from a boat rolling on the waters off Alaska's Kenai Peninsula might wish for image-stabilized lenses. But I didn't need them. I was shooting with the shake-beating camera body of Sony's new Alpha 100 DSLR. This meant that every lens I put on was, in effect, a stabilized lens.
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: 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.
