This series looks at the sharpness of the Zeiss Otus 100mm f/1.4 APO-Sonnar at medium distance in 187 megapixel Multi-Shot High-Res mode, evaluating focus shift in the process.
This series is a serendipitous one in showing how a focus shift can work out to great advantage in the right circumstances by good luck. But it can go the other way too—a great loss of sharpness. See the Otus 100/1.4 Focus Shift page for background as well as Backyard Trees.
