Sigma dp0 Quattro review – Noise

Google Preferred Source Badge

At low ISO sensitivities the dp0 gives exceptionally clean, detailed images. But things start to go wrong at higher settings, and JPEGs are practically unusable at ISOs of 1,600 and above. Raw images aren’t so bad, but they show exceptionally high luminance noise. ISO 6,400 is very poor indeed, with visible banding and colour blotching.
