DxO Labs got their hands on a pre-production Canon 550D / T2i for testing. I put up the results against a Canon 7D.
The results between the 550D / T2i and 7D are almost identical. The 7D slightly beats the 550D / T2i in the “Low-Light” category. For the other categories the differences were nominal.
This first tab shows product specifications and DxOMark Sensor scale and metrics results. The second tab, ISO Sensitivity, shows the differences between the manufacturer's published ISO sensitivity values and those measured by DxO Labs (following the ISO #12232 standard compliant method). As the ISO Sensitivity setting has a strong influence on measurement results, all subsequent Image Quality measurements are provided using the standards-compliant DxO Labs ISO sensitivity values for Signal-to-Noise Ratio at 18% mid-gray level (SNR 18%), Dynamic Range, Tonal Range, Color Sensitivity, the complete set of SNR curves (Full SNR), and (in the tab marked Full CS) the noise covariance ellipses used for assessing Color Sensitivity.
