DOF is determined by the FL, not the sensor format. Other solution to the busy issue..... retire. Then you can do this all day long. Frank Filippone red735i@earthlink.net Steve, I would love to have seen French [woman] near blackboard shot at f/5,6, if possible. To see the difference in contrast/sharpness. Wide open the DR's contrast is noticeably softer than curent Leica lenses; at 4 and 5,6 there is very little difference. Also interesting in this imge is the effective focal length of the 50 Summicron - 70mm - but with the depth of field/focus of a 70mm., to be exact, 69.2mm I may have to begin LUGging by digest; finding it difficult to deal with 150-200 emails a day :-( while still practicing law and other things! :-)
