2.
Adjust the lens zoom ring until the plate width just barely fits in between the short vertical zoom
markers on the display.
3.
Have your assistant tape the lens front-focus chart to the stand so that it appears in-between the
zoom markers. Make sure the black and white bars are vertical in the image.
4.
Carefully adjust the lens focus ring until the focus bar waveform display is maximized in amplitude
spread. The “Focus percentage” display shown on the left side of the “Focus Bar Waveform” win-
dow should then be maximized when the picture has got the best focus. If necessary, readjust the
zoom and focus until the width of the plate is just inside the zoom markers and the waveform
spread of the bars is maximized.
