1) Open the images shot with the checking lens and the AE master lens by the image display software on the PC. (Display the images at
the same pixel magnification.)
2) Check the displacement between the focus position (peak of image-formation) of the checking lens and the focus position of the AE
master lens. (Refer to Fig. 4-6-4 and Fig. 4-6-5.)
3) Compare the error amount in step 2) with the reference value of Table 4-6-3 and check whether the error amount is within the accept-
able range. If the error amount is outside of the range, perform 4-11-3.

• If the peak of image-formation is to equal distance with AF assist chart position, it is ideal. In actual fact, the image of before and
behind the peak is displayed. (Because the environment, the individual difference of camera and lens conditions are combined.)
• The image of before and behind the peak, assume it reference standard image.
• When shooting the image with sharpness setting of the camera to + side, it is easy to distinguish the peak of imaging area remarkably.

Example of decision:
The checking lens has a tendency of backward defocusing compared to the AE master lens. The error amount is approx. 14 cm.
Compare this error amount with the reference value and check whether the error amount is within the acceptable range.
If the error amount is outside the acceptable range, perform 4-11-3.
