Additional details about test data results of Fujifilm super CCD cameras (S5 Pro, S3 Pro…)
The measurements for Fujifilm Super CCD cameras are qualitatively different from those for other DSLRs, given that the Fujifilm Super CCD cameras sensor uses super CCD technology: instead of just one sensor, two sensors (of 6Mpix each) are interleaved on the die.
Each sensor has a Bayer structure, rotated by 45°. However, one has large pixels with sensitivity comparable to any other DSLR sensor, and the other one has smaller pixels with much lower sensitivity (about 4 f-stops). The advantage of this second sensor is that while highlights might be burnt on the large pixels, they still contain some information on the small pixels. This means that a significant gain can be expected in dynamic range.
This special “dynamic boost” mode is available for ISO settings lower than 800.
In order to be able to compare the Fujifilm Super CCD cameras data with that of any other sensor, we had to adapt our standard protocols:
Our results showed:
