Starting to get reports from people who have upgraded, but do not have the problem. You may want to skip down to the discussion section at the end of the page and start there if you are new to this issue. In the following table, I have measured the actual focus distances against the manual focus settings. This was done after the 1.1 upgrade on my camera. A quick check shows that the distances are the same after the 1.2 upgrade.
Distances are in feet.
I could not judge the focus on the more distant wide angle shots very well. I used wide open aperture to maximize depth of field. I made this table by photographing chalk marks on the ground for the more distant settings, or by using a ruler for the closer observations. I tried to visually estimate the center of the focused area. It would be possible to do this in a more controlled manner, but I feel that these results are pretty good.
