Lesson Goal: This is primarily a hands on lab lesson. This lesson will give you experience in disassembling, repairing and reassembling a lens. As in other lab lessons you will be required to apply many of the skills you gained in earlier lessons. When you complete this lesson you should have confidence in your ability to disassemble and reassemble any lens.

The lens selected for this lab is more difficult to disassemble and reassemble then most designs. There is a reason for this. Typically when repairing lens, technicians have only a minimal amount of information, usually the manual is little more then a parts list. Technicians working on lens have to rely heavily on the experience and ingenuity.
