Lens Calibration

[dericcainphoto]

I have a 7D and I use a 24-70 2.8L and 70-200 2.8L IS II. Both of the lens seem to focus fine when zoomed in, but when zoomed out, they both miss focus. I do not see how micro adjustment would help this. Has anyone had any luck with any calibration services? I have missed too many shots to not do something about this. Thanks in advance for your help.
