one thing to note here... when i did the 50mm lens tests, i noticed that there was severe focus shift coming off of f/1.4, on all 4(?) of the legacy pieces of glass that i shot... you can't see it with an ovf, but at 14.3x magnification on an evf, it's clear as day.
you should be able to see it on a pentax lcd, that has magnification? test for it on your gear.
so when opening up to focus, don't go all the way open, even one click above f/1.4 had much less focus shift... i was focusing probably 100 yards away, and there isn't any infinity focus stop with adapted lenses on the a7r.
