Several posters have noted the same thing that Bill mentioned: fussing with the zoom and missing the moment. That problem goes away when I use a 28-35-50 Tri-Elmar. It does not focus correctly between the three main focal lengths, which makes choosing which length to use very easy. At f/4 it works well except when the light fades, so I have Summiluxes for those conditions. Don't have the wide Tri-Elmar, as I don't shoot wide-wide, but I sometimes wish Leica would make a 75-90-135 f/4.
