Sounds weird that you'd have a misbehaving AF point on your E-M1. With DSLR PDAF such a diagnosis makes sense but how could one even hypothetically explain such a thing with mirrorless CDAF?

I'm baffled. But it's repeatable with different lenses and different focus distances. That one point just won't focus properly. Even choosing large vs. small AF point sizes makes no difference. I think I'll give the sensor a cleaning & see if that corrects it.

Many thanks at any rate for redoing the test. While the 25/1.4 at f/1.4 can be expected to be inferior to the 50/2 at f/2.8 for sharpness, its inferiority can hardly be expected to be quite as pronounced as it initially appeared.

I should've caught that before posting. The PanaLeica at f/1.4 is indeed very good, as the redo shows.
