Your lens did not report focus distance

[atopin]

I installed ML v2.3 in my canon eos5d mark2.
I am trying to use Stack focus, but Focus menu in ML tells me "Your lens did not report focus distance".
I have some canon-made lenses such as ef24-70mmf2.8 L USM, ef100mf2.8L IS USM macro, and ef16-35mmf2.8L II USM.
None of my lenses makes me use Stack focus. Please help me why?
Sorry about my English. I am japanese.

It does not matter if your lens reports focal distance. You can still use focus stacking. I am almost done with a video tutorial that covers focus stacking. It should be done and posted tomorrow.

If you are not in LiveView no lens will report focus distance.
