A brief introduction to focus shift

Canon 50mm f/1.2L and/or 85mm f/1.2L image are soft?
Sigma 50/1.4 soft?
Nikon 50/1.4 images soft?

Focus was on the eye at right. Why is it blurry?

If you shoot a “fast” lens, you might be erroneously concluding that it’s not sharp. Understand why in my Introduction to Focus Shift, or get the full report on seven different 50mm lenses in DAP (with 85mm lenses planned too).
