[QUOTE="BackdoorArts, post: 115166, member: 9240"] Take a photo at chosen focal length and minimum aperture (for a zoom, select a most used length or max extension - my rule as zooms may vary throughout), using something that will allow you to check for front or back focus. In the Setup Menu, go into AF Fine Tune, then into the Saved Value, and then choose an arbitrary starting point (+ for front focus, - for back focus, we mathematicians choose to go binary search on you and start at +/-10 and then go half way between the gaps in successive tries), shoot another photo, compare and do it again. The camera will remember that setting for the particular lens. If you find the camera has a bent towards always going one way or another then you can set a default for all lenses (I prefer not to and just profile each one - you can save 12). Here's a video that will walk you through it using something other than a calibration chart.
