Bill, Hopefully the R 'solution' will include some kind of focus confirmation in the viewfinder. I have mounted R glass on my digilux 3 and focus confirmation is quite sensitive and accurate to the point where I can see no difference between auto focus mode or when taking the same shot in manual mode. When the green light appears in the view finder to confirm focus the shot turns out just as sharp. I haven't yet tried this with the 80-200 but will do so soon. So far I have only mounted the new lens on my Sigma SD14 and the focus confirmation capability of the Sigma is poor and unusable. The issue with focus confirmation as far as I can see is that one has to work with one single point of focus, the camera will only confirm focus at the centre of the viewfinder. Maybe that's not an issue as the centre is what usually counts when using tele lenses. Walter On Tue, 2009-08-04 at 17:36 -0700, William B.
