Quality of Focus (QoF) is plotted against AF Microadjustment on the lens profile graph on the bottom right of the calibration window. Points are validated (an orange dot is placed inside the red diamond) when a number of the test shots at that same AF Mircoadjustment value are within a certain percent.
Values of “Poor”, “Acceptable”, “Good” or “Excellent” are used within FoCal.ĭuring an Automatic Focus Calibration FoCal takes a series of test images at different AF Microadjustment (auto focus fine tune) values to determine which setting will provide optimum results for that particular camera/lens combination. Fit Quality or Result Confidence is a measure of how well the individual validated test points on the lens profile graph match up with the expected behaviour of a normal lens.
