In the original release of D2:ED the camera distance was farther out, and using Target Lock zoomed in to about where it is is DKS; In DKS the camera distance is fixed regardless of Target Lock.
For the PC version of DKS, you could use the mouse to zoom the camera in or out (with the camera angle linked to the distance). I don't know if there were any changes to the camera in the PC version of DKS.
The videos displaying the skills can ignore cooldown times and other limits, so presumably the same is true for the camera distance.
