2x
It's not the lens that does it, it's the sensor size.
Any lens you put on a m4/3 camera is going to look like it's twice the length than if you were to mount it on a "full-frame camera.
A 50mm is a "normal" lens on full-frame but on an m4/3, it will have the same field of view as a 100 on a full frame camera.

I kinda like the idea that if your monitor was a full frame sensor then a crop sensor is like you put cardboard on the sides the picture is the same, same depth of field still focused at the same point you just don't see as much as its cropped down.
isn't that simple :)

The best kind :-)

Use the lens designed for it no crop factor. If you say the M4/3 has a crop factor of 2 then what's the crop factor of the Hasselblad H5?

.5
Next question.
See second image.

It's not the same depth of field. The depth of field is 2X the DOF for the lens on a full frame body.

Does it mean that MFT 16mpx = FF 32mpx ?
There's more to it than that...it also has to do with the size of the pixels and their light gathering properties.
That said, the new em5ii with 40mpx sensor shift technology should be interesting, especially if it produces a RAW 40mpx file...but I'm guessing it will only be a 40mpx jpg.

No I don't think so

I read that as to get an identical picture on a full frame v a crop sensor camera Then you have to move the (aps) camera further back with the crop sensor as you have a narrower angle of view because you changed the subject camera distance the dof changed. Had you not moved the camera and accepted the closer crop of the camera making your subject occupy more of the frame then the dof has to remain the same.
Consider a nikon d800 mounted on a tripod facing a subject if you switch between fx and dx how can the depth of field change?.
