UPDATE April 2: Hasselblad has confirmed the issue and is working on it. It involves the way autofocus interacts with the spatial frequency of the subject, which fits perfectly with my field observations of the shooting situations that saw an issue.
See yesterday’s post for details and discussion, including independent confirmation with the 30mm, 45mm, 90mm lenses by a reader.
Now updated with five additional examples:
I am working with Hasselblad and expect to have an alternate X1D and 90/3.2 in 2 weeks or so to also test, but Howard’s comments seem to rule out a single-camera or single-lens issue and support my original findings in every way.
