Canon Digital Learning Center published the Canon EOS AF Microadjustment Guidebook, and made it available for free. You can download the Canon EOS AF Microadjustment Guidebook it here. The guidebook comes as PDF file or mobile version.
AF Microadjustment has been a feature in mid-range and high-end Canon EOS D-SLRs for some time now. But there have been questions, and more than a little confusion, about the best process to test and perform these adjustments.
Canon Inc. engineers have provided a guidebook that shows the steps a typical camera owner can perform to indeed test his or her lenses, and determine whether adjustment is needed. And, it describes how to carry out the adjustment procedure. This guidebook applies to any Canon EOS digital SLR with built-in AF Microadjustment, and applies to all Canon EF and EF-S lenses. We hope it clarifies some points for our customers, and shows that the Microadjustment procedure doesn’t need to be a long, technical process.
The guide applies to all Canon DSLRs featuring AF microadjustment.
