<For reference 2: The example of focusing error amount value check> (Fig. 4-5-5)
Check the displacement between the focus position (peak of image-formation) of the lens to be tested and the focus position (peak of im-
age-formation) of the AE master lens.

Example of image shot with lens to be tested (50 mm F1.4)

Example of image shot with AE master lens

Peak area
(existing around 7 to 8 cm
of the rear scale)

Peak area
(existing around 6 to 7 cm
of the front scale)

Error amount = approx. 14 cm

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.
