We saw plenty of bloggers and photographers posting their Sony A7rII tests. But it’s time now to get a feedback form a different kind of reviewer. What does electrical engineer Kasson think about the new Sony camera? His principal research area for those six years was color management, color processing for digital photography, and color transformations such as gamut mapping. And these are damn great and must-rad articles you have to click on:
