PhotoAgainst Photo Editor's Comment: In our official ISO test we shoot a chart that consists of 1 and 5 American Dolars. We take 6 crops from various sections of the chart to display details in different ISO.
For each camera we shoot a good quality lens in its sweat spot This is usually F8 for interchangeable lens cameras.
Unlike our other comparisons, these ISO shots are taken in different times and lighting conditions might be different. So please consider only ISOs in these tests (we recommend analyzing black and white crops we provide) as contrast and color cast might not be very accurate in these comparisons.
After reviewing the test, scroll to the bottom of the page to compare Sony A55's ISO with other cameras.
