John, calibration usually refers to adjusting your camera/monitor/printer to capture, display and output/print colors in a consistent manner, but I think you *might* be actually thinking about having your camera and lenses examined (typically by Canon) to insure that neither has any focusing problems, especially back focus. There are some tests you can perform yourself, here's a simple one"
(http://www.photo.net/bboard/q-and-a-fetch-msg.tcl?msg_id=009wR4) While there are certainly cameras and lenses with focusing issues, I think there are more issues with people not understanding the what results from using multipoint focusing systems or even more basic operational issues. Costs of adjustment for cameras and lenses are going to vary based on the specific lens and warranty status of the items that might need work.
