un petit extrait sur le bruit : "
"The camera produces admirably clean files between ISO 100 and ISO 400. ISO 800 will depend heavily on the lighting, whereas ISO 1600 clearly exhibits noise at 100% viewing. The situation gets worse at 3200, while the expanded setting of ISO 6400 looks rather nasty up close. We have provided, as usual, a set of 100% crops, but with the photos produced by the A900 being nearly 25 megapixels, it is imperative that we point our how small a portion of the full frame these crops represent. Therefore we urge you to judge them accordingly – remember that no matter how ugly the ISO 6400 crops may look, they still retain more detail than most other cameras can capture in the first place."
