Hi Wing,
I too read the same post and checked out what was happening as I had just got the new 35 f2 and noticed the difference. In short after some testing the xpro1 and 35 f2 are working correctly as the corrected af frame shown for the f2 is where it should be for a lens with only one min focus distance and this is 35mm for the f2.
It is confusing when you also have the f1.4 because that lens like the other older lenses have two min focus distances but the ovf is showing a corrected frame for only one of that lens min focus distances. The one for when the xpro is not set in macro mode. As the non-macro distance is 80cm for the f1.4 the corrected frame displayed is also correct (macro min distance is 28cm). And why it is closer that the f2 frame is because the min focus distance is further away so less parallax effect to correct for. It is not to do with enabling easier detection of where the focus point is.
In summary the f2 can be used at min focus with the ovf parallax correcting correctly. As can the f1.4 at its non-macro min distance. To get to the f1.4's min (macro) distance you need to set the xpro to macro mode which automatically switches to evf.
If you also own the XT1 then it is also confusing because the f1.4 behaves on that body (post firmware update removal of macro mode ) as if it only has one min distance of 28 cm, hence why it seems slow on that body compared to using it on the xpro1 as it has to run its full focus length at all times now.
Both lenses are worth having if you can because one is one stop faster and closer focusing and one is quicker in operation and weather resistant. So really two very separate tools.
For all the testing details I did see Rediscover Films YouTube post on the issue.
