Verdict

The Sony A100 is an entry-level DSLR featuring a 10.2-megapixel APS-C CCD sensor and the Sony/Minolta Alpha lens mount, inherited after Sony's acquisition of Konica Minolta. Key technical characteristics include 'Super SteadyShot' in-body image stabilisation, a 9-point autofocus system with 'Eye-Start' activation, a 40-segment honeycomb pattern metering system, and a 2.5-inch 230k-dot LCD screen. Its primary advantages are the CCD sensor’s nostalgic colour reproduction, excellent broad lens compatibility with legacy Minolta glass, and an effective anti-dust sensor vibration system. However, the camera suffers from significant image noise at higher ISO settings (ISO 800–1600), a relatively slow 3fps continuous shooting rate, and a lack of modern features such as live view or video recording.
