I am not sure which camera you are using.... some allow the "in focus" FP
range to be adjusted.  Read the manual if you are not sure.

I do not use focus peaking.. I use the magnification feature, and do the
equivalent of ground glass focusing.  Lots of fun to watch the focus move
THROUGH the eyeball.... GG focusing is excellent because you watch the focus
change,,, and therefore get in focus what you want, precisely.

In general, and I think Steve Barbour said it, that EVF make the hard to
focus lenses easier, and the easy to focus lenses harder.....  The issue is
DOF at focusing aperture.
Use faster lenses, open the lens for focusing then shut down to working
aperture ( a genuine PITA that I gave up when I was 13, and do not wish to
go backwards), or just shoot wide open....

Remember, you are using the sensor to focus... any focus errors are
yours....

Hi Stan,
Typically, I set the focus peaking at low which minimizes the peaking over
shoot.  What you will find yourself doing is upgrading your wides to ones
that have a very high inherent contrast such as the newer Leica M wides.

I have had great luck focus peaking with the 24 Apo Elmarit and the 21 F1.4
.  Using the 21 R lens I get the same result that you are getting; I have
found that I set the focus distance by scale and confirm by peaking.
