I can say that if you send one into DAG for focus adjust, he'll ask you where you want to optimize as there is focus shift. Mine is so "on" at 1.0 I'm quite happy, but if it drifts, I'd optimize it for 1.0-2.0 (he claims that is reliable) and leave 2.8-4 for other 50 lenses. I really never use the nocti past 2.0, almost always at 1.0 in any event. I'm sure by 5.6 it would be fine anyway, and I'm sure that many excellent images are made with this lens from f1-5.6! best...Peter
