Replace damaged parts

If your DSLR camera lens has any damaged parts that cannot be repaired, you may need to replace them. Commonly replaced parts include the lens barrel, lens mount, autofocus motor, or any other mechanical components that are beyond repair. To replace these parts, you will need to disassemble the lens carefully, remove the damaged components, and install the new parts following the manufacturer’s instructions.
