Sony Alpha DSLR-A100 is an impressive debut that pairs a 10.2-megapixel sensor with built-in anti-shake technology for a competitive price. While it offers responsive handling and decent build quality, the camera struggles with high ISO noise and occasional metering inconsistencies.

    The Sony Alpha A100's 18-70mm kit lens produced slightly soft corners in a few shots, with the strongest effect at full telephoto.

    There’s no denying Sony’s Alpha DSLR-A100 is an impressive camera for the money. Simply having 10.2 Megapixel resolution and built-in anti-camera-shake is enough to elevate it beyond most budget digital SLRs.

  • Popular Photography

    The merger of KM into Sony appears to have produced a better DSLR than either company could have made on its own, with features and a price that should attract anyone ready to move up from a compact or EVF digital camera to their first DSLR.

    The quality of images produced, coupled with the range of features packed into a compact SLR body certainly make Sony's début worth serious consideration.

    An extremely impressive debut from a new player in the digital SLR market, the Sony Alpha α100 is pitched at the consumer end of the market, but is actually a better camera than most of its mid-range rivals too.

  • Pocket-lint

    It’s simple to use, offers high-resolution images and has plenty of handy kit built in. And while it feels, well, a tad clunky it’s an excellent bit of kit well worth a look.

  • I think the Sony A100 is competitive in general performance with similar cost Canon and Nikon bodies, though the noise level is slightly higher at high ISO settings. However for most users I think the built-in stabilization system may often more than makes up for that.

    [F]or the price you can get a Sony Alpha DSLR-A100 nowadays, I think it can still be a good buy, especially for someone eyeing some vintage Minolta glass on a budget.
