Does Canon 24-70 lens have infinite focus?

It should be said that each camera lens has infinite focal length, that is, the lens receives parallel light, just like on the focal plane of the lens; If the object is not imaged at infinity, it is necessary to adjust the distance between the lens and the imaging plane (CMOS sensor of the camera). This process is called focusing.

This is the first and second generation photos of 24-70mm2.8L. We see that the ∞ coincidence degree at the far right of the focal length is infinite.
