About auto focus calibration...
Hi, I have a T5i not in the list but basically the same to the T4i, and this will probably apply to anu rebel camera.
Higher grade camperas have focus trim options for each lens, rebel camera don’t, but canon provide the service of calibration, so the camera is capable of doing it.
My question is of somebody knows the method and if there is some way to archive it at home. It worth mentioning that I kniw my electrónicos and pinching in an interna conector and comunicating that way wouldnt be a problema.
Best regards and thanks!
