Lesson Goal:This lesson teaches various auto-focus methods used by cameras. The primary focus, pun intended, is AF CCDs used in film and digital cameras. Autofocus systems used by digital camera are basically an improved version of the same CCD technology used by film SLRs. Mostly the improvements are technological and have not changed our repair and adjustment procedure significantly.

When you complete this lesson you should be able to troubleshoot and service Autofocus problems on most cameras. You will also be required to perform addition lab exercises on SLR cameras provided in latter lessons.

Hands On Lab P/S Camera, test the AF system. SLR Camera, test the AF system Typical Time Required: 12 hours
