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...
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.
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
Summary: The entry into the SLR market for a first timer is daunting but by buying Konica Minolta’s SLR division Sony aren’t taking any risks. The feel of the A100 is a bit plasticky, but the finish has been enhanced with Sony’s trademark silver function dials on the top-plate. But it has a great anti-shake and anti-dust system.
