Before Disassembly / Reassembly / Adjustment
This lens will require optical lens alignment after assembly, in case the 4th lens-group unit is removed.
At repair service facilities, therefore, where this alignment work can not be performed, do NOT remove the 4th lens-group unit.
This lens also has the VR (vibration-reduction) unit mounted in order to correct camera shake.
To keep the accuracy of this function for stabilizing the image, in case VR unit or the main PCB is replaced, be sure to make the VR adjustment by using the VR lens adjustment equipment (J15380).
Except for disassembling the above components, the VR adjustment is NOT necessary, but check VR operations by attaching this lens to the camera.
At repair service facilities where the "VR lens adjustment equipment" is not prepared, do NOT disassemble NOR repair the products of the above cases.
Caution:
When disassembling/(re)assembling, be sure to use the conductive mat (J5033) and wrist strap (J5033-5) for static protection of electrical parts.
When disassembling, make sure to memorize the processing state of wires, screws to be fixed and their types, etc.
Because prototypes are used for "1. Disassembly" and "2. Assembly/Adjustment", they may differ from the actual products in forms, etc.
Because pictures are processed by a special method, they may differ from the actual ones in texture.
Points to notice for Lead-free solder products
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.
