The ONLY place that mirror/diaphragm vibration is a problem is at 1/15, 1/12, 1/8, 1/6, and 1/4 sec. Anything faster and anything slower does not "capture" the vibration. This is a well known phenomena in ALL SLR (except for that Canon thing) cameras. George Lepp did an entire issue of his newsletter on this "problem". George tested Canon and Nikon, perhaps others, but not Leica. I know it exists in Leica and I know how to eliminate it. This is one reason I no longer use the R4sP. No MLU.
