Is there any way except focus magnification to improve the precision of the manual focus using peaking? When I used a Nikon FM2 the center prismatic focus aid was very crisp and with no slop. But the color peaking in my a6000 requires me to move the focus back and forth to find the center of a range of focus distances. I already use the most precise setting and both yellow and red depending upon the color(s) of the subject.
