Tim, that was using HHT mode for noise stacking. ; It was still tough with a manual lens and no stabilization, which is why it's not quite as razor sharp, and the lens I was using is very sharp on center at F1.4, but does suffer corner softness wide open like that. ; I hadn't used the lens much at all, so it was a learning experience - I later figured out that at F1.8 or F2.0 I could get much better corner results, and with HHT could still have enough light to get away with handheld...that was only ISo2500 so I had plenty of room to go higher.
