Dice questo:
"From the 100% blow up results above, you can see that these high resolution claims are no idle boast. Either from raw or jpg., both cameras produce very detailed, very high resolution, very sharp files. There are differences in colour balance and the Sigma has a worse dynamic range, but overall if you are interested in produced files with mind boggling sizes (The Olympus raw is 9216 x 6912 pixels and the Sigma an astonishing 10848 x 7232 pixels !!!!) I would also point out that only the basic default sharpening was applied to the raw files and the jpgs. are straight out of the camera with no editing. "
