How peculiar... "Improved precision of focus when using single focal length lenses". What could have brought this on?
Interesting, alright. Do I recall correctly S-AF uses CDAF? Perhaps they improved S-AF on the new camera and are back-upgrading earlier models?
Will install and see what's what.

I have a Pro shoot this weekend, so will wait until after then. It is even more interesting that the EM10.4 and EP7 gets the update... CDAF only bodies.
I am hoping to see an improvement with my 300 Pro... current focus accuracy is not as good as I would like.
The update note refers to focus precision not accuracy.
Even without Japanese to English translation errors the two terms are often used and misused interchangeably with the correct usage often depending on the context.
Accuracy of focus usually refers to correctness - front or back, and precision refers to how finely you can place focus on a small point - eg eye instead of head.
Exactly which OMDS is referring to here isn’t clear, but I’m hoping it’s the ability to pick out a small target without the camera grabbing focus onto something else nearby.
Why this would be specific to prime lenses and whether it’s a PDAF, CDAF, S-AF or C-AF thing or some combination is anybody’s guess.
My guess is that it’s a bug fix, and perhaps specific to certain lenses, not a performance enhancement.
