I have here a 70D (allows micro focus adjustments) and a 100mm 2.8 macro (non-L).
I take a photo or a bug and it's slightly out of focus (very slightly, but makes a huge difference on macro shots). I take one of those images that look like a rules for focus calibration, open on my ipad, place the camera on a 45 degree angle and snap a shot. I notice that it's back focusing a little bit. Then I adjust the micro AF until I can nail the focus on that scale (adjustment number is around -5).
After that, I go back to bug and shoot an ant - the camera is front focusing, so I keep shooting the ant and adjusting the focus and once again I'm at the zero mark for micro AF adjustment.
Any suggestions to get this focus properly adjusted?
I don't have focusing problems with other lenses, so it's not the camera body.
