That you take several shots because as I said, some shots will hit the mark. But often enough it doesn't (like 40-60% it doesn't). I also thought on EM5.3 at first it was "fixed" until I kept using it.

I still think this is an issue OMDS/Oylmpus should work out.

I found it to be repeatable over a number of shots in poor light, just like the test with the EM1.2. The EM1.2 consistently failed and EM1.1 passed. I also had the EM1.1 refusing to fire when it couldn’t lock focus in poor light with limited vertical contrast.

That'g great then. You have a reference baseline for the experiment (EM1.2) that fails and the EM1.1 is passing. I guess the EM1.1 is the one and only Olympus able to use this lens right. Maybe some other "back in time" Pen

Thanks for the update.

I think the EM1.1 has a unique AF system, unlike any later Olympus PDAF body.  That’s why it occurred to me to try it, along with no recollection of this issue during extensive use of the 20/1.7.

As a bonus, I’m reminded how much smaller and lighter the EM1.1 is and how much I still like the Zuiko 14-54mm.
