2)  Set the camera and chart for checking the depth area of image-formation as shown in Table 4-6-2, Fig. 4-6-1 and Fig. 4-6-2.

Shooting distance is obtained by shooting magnification and focal length as following.

 

[Shooting distance] = [shooting magnification] 

×

 [focal length]

Select the combination according to the Table 4-6-2 Guidelines table.

  If the shooting distance using a 60 times chart cannot be ensured indoors, temporarily use a combination of 40 times chart or 20 

times chart.

2. Shooting procedure
1)  Click the [Start] of Defocus Checker 2 or DSLR-A700 Defocus checker to start the measurements.
2)  Adjust defocus value to obtain  0 

μ

m  in the manual focus mode.

 

The tolerance is  0 

±

 10 

μ

m . (Fig. 4-6-3)

3)  Click the [Stop] of Defocus Checker 2 or DSLR-A700 Defocus checker.
4)  Shoot an image by self-timer.
5)  Perform the steps 1) to 4) by using the AE master lens and the lens to be tested.

Shoot images with the AE master lens and the lens to be tested using the same camera.

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.

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.

 

 

 

 

Use 35 mm full size type camera (SLT-A99) and 40 times chart. (When using the 40 times chart, shooting distance can shorten to 
2/3 of 60 times chart.)

 

 

 

 

Check the focusing error amount of short distance using 20 times chart temporarily. After that, shoot the something images out-
doors in the middle distance for using 60 times chart, and then check the focusing amount of middle distance.

3.  The focusing error amount check
1)  Open the images shot with the lens to be tested 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 lens to be tested 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 acceptable range. If the error amount is outside of the range, perform  4-8-4. Focusing Error Amount Adjustment (Write

<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 com-
bined.)
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 image-formation) of the AE master lens.

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  4-8-4. Focusing Error Amount Adjustment (Write 

⊿

SB) .

2.  Startup of Lens Adjustment Program (ActuatorCheckerSAM)
1)  Turn on the personal computer and the finished inspection JIG II.
2) Start up ActuatorCheckerSAM Ver X.XX.exe  from an arbitrary folder.

At the first time using, the followings appear on the screen (Fig. 4-7-2).
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. 4-7-3).

1. Start 

up ActuatorCheckerSAM Ver X.XX.exe .

 

2.  When the Japanese window appears, click the [Setup] button, change the language to English.

Depending on the initial startup or setting made at the previous startup, the window differs.

3.  Set the following contents in the SETUP window.
