SAL1118 (4.5-5.6/11-18) (DT 11-18mm F4.5-5.6)
4-4-2. Flange Back (f’F) Adjustment
Equipment
• 1000 mm Collimator
• Flange Back Tester
• A-mount Attachment
• Flange Back Gauge (43.50mm)
Note:
“4-4-3. Focus-shift Adjustment” must be completed before performing the Flange Back (f’F) Adjustment.
1. Preparations
1)
Remove the focus rubber.
2. Adjusting Method
1)
Perform “4-4-1. Flange Back (f’F) Check”, and check that the flange back (f’F) of the checking lens is out of specification of Table
4-4-1.
2)
Set the zoom ring of the checking lens to Tele end position (focal length: 18 mm)
3)
Set the support barrel assembly of the checking lens to over infinity position.
4)
Turn the knob of the flange back tester until the chart image is the sharpest while looking through the microscope.
5)
Calculate the shift amount (x) using the following formula.
Shift amount (x) = Measured value - 44.70 mm
Measured value: Flange back f’F at over infinity position (focal length: 18 mm)
x = Shift-amount that should be adjusted by the back adjustment washer.
6)
Adjust the back adjustment washer thickness according to the result of step 5). (Refer to Table 4-4-2.)
Note:
Be sure to measure the thickness of the back adjustment washer by micrometer or vernier caliper.
• When the shift-amount is a negative value: Decrease the back adjustment washer thickness by the amount of shift amount (x).
• When the shift-amount is a positive value: Increase the back adjustment washer thickness by the amount of shift amount (x).

4-4-3. Focus-shift Adjustment
This section describes the check/adjustment of focus-shift amount resulting change of the focal-length by zooming.
Equipment
• 1000 mm Collimator
• Flange Back Tester
• A-mount Attachment
• Flange Back Gauge (43.50mm)
Adjusting Method
Note:
Note:
About the insulating tape in the sentence. When shipping it, Mending tape (2-886-794-01) is used.
1)
Perform “4-4-1. Focus-shift/Flange Back (f’F) Check and Optical Axis Adjustment”, and check that the flange back (f’F) of the
checking lens is out of specification of Table 4-4-1.
2)
Set the zoom ring of the checking lens to Wide end position (focal length: 11 mm).
3)
Set the support barrel assembly of the checking lens to infinity position (center of the “L” mark index). (Fig. 4-4-6)
4)
Turn the knob of the flange back tester until the chart image is the sharpest while looking through the microscope, and check the
flange back (f’F).
5)
Set the zoom ring of the checking lens to Tele end position (focal length: 18 mm).
6)
Peel off the two insulating tapes. (Fig 4-4-6)
7)
Turn the support barrel assembly until the chart image is the sharpest.
8)
Set the focus gear barrel to the infinity position (infinity end) while maintaining the support barrel assembly so as not to rotate it.
Affix the two insulating tapes. (Fig 4-4-6)
9)
Perform steps 2) to 8) until the specification of focus-shift amount (difference between the maximum flange back (f’F) and minimum
flange back (f’F)) of the checking lens is met.
Focus-shift = Maximum flange back (f’F) reading - Minimum flange back (f’F) reading
Specification
Focus-shift: Less or equal 0.03 mm
