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. See the Otus 100/1.4 Focus Shift page for background.
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.
Which makes this series illuminating in showing how understanding lens behavior and biasing focus slightly can result in considerably superior total sharpness captured. Anyone shooting the Otus 100/1.4 should find this series invaluable in getting the best results from it consistently.
