Removing the 1-1st lens group or 5th lens group of this lens needs the lens alignment work after the assembly.
Therefore, at service facilities where the lens alignment cannot be performed, do NOT remove the 1-1st lens
group nor 5th lens group.
On this lens, the VR (vibration-reduction) unit is mounted to correct the picture blur.
In order to maintain the functional accuracy of the picture blur correction, if detaching the VR
(vibration-reduction) unit and gyro base plate or if removing the main PCB unit, be sure to adjust the VR by
using the VR lens adjustment equipment (J15380）.
However, if disassembling the parts except the above, the VR adjustment is NOT necessary.
At service agencies where the "VR lens adjustment equipment" is not prepared, do NEITHER disassemble
NOR repair the products of the above case.
Caution:
① When disassembling, make sure to memorize the processing state of wires, screws to be xed and their types, etc.
②Because prototypes are used for "Disassembly/(Re)assembly/Adjustment", they may differ from the actual
products in forms, etc.
③ Because pictures are processed by a special method, they may differ from the actual ones in texture.
・Lead-free solder is used for this product.
・For soldering work, the special solder and soldering iron are required.
・Do NOT mix up lead-free solder with traditional solder.
・Use the special soldering iron respectively for lead-free solder and lead solder.
They cannot be used in common.
Points to notice for Lead-free solder products
