Appreciate your detailed post.

Note that I have no problems whatsoever with the center; all handheld.

If I use identical technique but utilize a lateral cross-type focus point it is always out of focus.

I'm pretty sure it is an equipment, not technique, issue.

Your advice remains very important to keep in mind in any case.

You are welcome. What you are saying definitely points in the direction of an equipment issue. Can you discern a consistent pattern in the misfocussing ? like for instance the same range of front focussing. Or is it random, back and front focussing ?

Not sure yet

Do you have another wide aperture prime lens to test on your camera ?

A 50 1.4.

On the body I had that had issues, you could see it with even slow lenses like 24-105 f/4.  If you are seeing it with slower lenses, too, it points to a camera problem.

And 5D3 is so consistent with it's focus, EVERY shot would be wayyyyy off.  Not just one or two shots here and there...

DFPanno, will you please update the thread when you have narrowed it down?  I'm very curious how it ends up working out.

Thx,

Michelle
