Before Disassembly / Reassembly / Adjustment

This lens will require optical lens alignment after assembly, in case the 5th lens-group unit is removed.

At repair service facilities, therefore, where this alignment work can not be performed, do NOT remove the 5th 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 the fixed ring unit (gyro FPC), main PCB unit, or the 3-4G lens group unit (VR unit) is replaced, be sure to make the VR adjustment by using the VR lens adjustment equipment (J15380).

At repair service facilities where the "VR lens adjustment equipment" is not prepared, do NOT disassemble nor repair the above-mentioned parts.

The VR adjustment is NOT necessary except for disassembling the above-mentioned parts.

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 "Disassembly", "Assembly", and "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.
