Best Praise

“The A100 was my first DSLR and I loved it. Great image quality and handling. If possible try not to go over ISO 400 if you want the best IQ, I remember it got very noisy going beyond that.”

Top Criticism

“My second Alpha, after the A100. Loved the ergonomics of the A700 (and its ISO performance, the A100 was shit above ISO 400). Good old times. OP, enjoy the camera. Plenty of cheap and great lenses (both Minolta and Sony).”
