The British Journal of Photography has published a review of the new Sony A900.
Sony’s first full-format camera is designed to meet the needs of ambitious amateurs and semi-professionals. JPEG compression is perfectly balanced, and input dynamic range at high ISO speeds is excellent. Tonal reproduction focuses on instant image appeal (rather than something more neutral, which you see with more pro oriented cameras), and the sharpening is OK.
