Just quick note, I’ve added a tedious but usable workaround for magnified Live View focusing that achieves 2X greater magnification.
The workaround has serious drawbacks that make it worthwhile only in limited circumstances., but you do get 2X larger (4X in area) magnification for manual focusing.
The workaround is proof that Panasonic could easily fix the issue in a firmware update. And that someone in Panasonic engineering has poor judgment shipping the S1R with such an arbitrary magnification cutoff.
