The Alpha A100 has a 2.5-inch LCD, its lithium ion battery is rated to last 750 shots on one charge, and the sensor moves both to remove dust and to fight blur in photos. The camera has a nine-point autofocus system and an eye sensor so the camera begins focusing as you put your eye to the viewfinder rather than waiting until you press the shutter button. The A100 takes CompactFlash cards, and comes with an adapter for MS Duo cards.
If all you're counting is megapixels, this new Sony delivers a lot for the money. Our lab tests show that a lot of megapixels alone don't ensure better photo quality over comparable cameras, though Sony also claims that the A100's new image processor optimizes dynamic range to improve detail in highlights and shadows. We look forward to testing this model, especially to see how well its noise reduction works at its highest sensitivity--ISO 3200. Many digital cameras that can shoot at such high settings deliver images with an excessive amount of digital noise.
Sony is announcing six lenses with the camera, and plans to introduce about nine more in a few months. A total of 22 lenses (mostly rebranded Konica Minolta lenses) will be available.
