<For reference 1: shooting image by AE master lens> (Fig. 4-6-4)
•  Assume it standard image in the setting environment.
•  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.

Enlargement of same pixel magnification

Example of image shot with 
a certain AE master lens under 
a certain environment.

Identifying the peak position of 
image-formation:
• Center of sharpest area
• Center of area with less color fogged
    - Front defocus area: Magenta fogged
    - Rear defocus area: Green fogged

Example where peak position accidentally matches 
the AF Assist Chart position

 

<For reference 2: The example of focusing error amount value check> (Fig. 4-6-5)
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  4-9-3. Focusing Error Amount Adjustment (Write 

⊿

SB) .

2.  Startup of Lens Adjustment Program (ActuatorCheckerSSM)
1)  Turn on the personal computer and the finished inspection JIG II.
2) Start up ACSSM-S-VerX.XX.exe  from an arbitrary folder.

Note:
•  At the first time using, the followings appear on the screen (Fig. 4-7-3).

It is required to ask HQ about the password for the Com/User Characteristic Number and the manufacturer/type name of the personal 
computer.
Ex.  Com/User Characteristic Number :  iYdDZfq9q
 

Personal Computer : 

SONY PCV-RZ33P

•  It is no need to input password to the computer once registered.

(The screen requires password does not appear.)

•  If the personal computer or the finished inspection JIG II is changed, the password and the Com/User Characteristic Number are 

changed. Therefore on the startup, the password input is required again.

3) Input the password and click [OK[Ent]], the following appears on the screen (Fig. 4-7-4).

1. Start 

up ACSSM-S-VerX.XX.exe .
