Attaching a Lens
 Chapter 2 Installation and Preparations
To change a shim
Exercise care not to damage the internal wiring of the 
camera when changing the shim. Modifying a shim, 
scratching a surface, or introducing dust can change the 
flange back distance and damage the camera such that it 
cannot be restored to original condition, just as for a film 
camera. 
1
Remove the lens mount screws (6). 
2
Pull the lens mount out by about 10 mm (
13
/
32
 inch) 
and remove the shim carefully. 
Pass the shim slit over the wiring, taking care not to 
pull the wiring, when removing the shim. 
Pulling the lens mount out by more than 20 mm 
(
3
/
4
 inch) risks damage to the internal wiring. 
3
Insert the replacement shim using the shim slit to clear 
the wiring, and align the camera screw holes and shim 
alignment pins.
4
Reattach the lens mount in its original position, and 
fasten the screws to a torque of 0.53 N·m (0.39 lbf).
