By using Tim Jackson's chart (thanks Rick for reminding me that!) I've got the following calibration settings for the K20D:
DA 12-24 = -6 DA 16-45 = 0 DA* 50-135 = -3 FA 31 = -10 (and it's not enough!) FA 50/1.7 = -10 FA 50/1.4 = -10 FA* 85/1.4 = -9 FA 24-90 = -6 F* 300/4.5 = -4 So my lenses are all front focusing, and not a single one is back focusing. Or maybe my K20D is acting that way. It will be interesting to know how much variation one can find with the same combos made up of different items.
