If you haven't done so already, you will want to test the 75 at nearest
focus, f1.4, on a tripod with both the Bessa T and an M6 body (.85x pref.).
Since the Noct focuses fine close and wide, I suspect your 75 may suffer the
same problem as mine (and other samples): at < 1.5 m, its focus begins to
creep closer than the RF indicates.  At .7 m, mine focuses a full 3 inches
closer than its target (as tested on two different bodies).
