5) Perform the steps 1) to 4) by using the AE master lens and the lens to be tested.
Note 1:
Shoot images with the AE master lens and the lens to be tested using the same camera.
Note 2:
Perform entire work within 10 minutes because values become unstable as the camera temperature increases.
If the work continues for 10 minutes or longer, cool down the camera and then restart the work.
Note 3:
Since focusing error amount increases in shooting images at a middle or long distance, comprehensive focusing error amount cannot be
determined correctly only by results with short-distance setting. If the shooting distance using a 60 times chart cannot be ensured indoors,
take either of the following methods.

2) Check the displacement between the focus position (peak of image-formation) of the lens to be tested and the focus position of the AE
master lens. (Refer to Fig. 4-5-4 and Fig. 4-5-5.)
3) Compare the error amount in step 2) with the reference value of Table 4-5-3 and check whether the error amount is within the accept-
able range. If the error amount is outside of the range, perform 4-7-5.

Example of decision:
The lens to be tested 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 4-7-5.
