MF is an abbreviation for manual focus.

Besides, what is AF and MF in DSLR?
On the side of your lens, look for a switch labeled "AF - MF," which is short for Autofocus and Manual Focus, respectively. When you're ready to shoot in MF mode, switch your lens to that setting. At this point, half-pressing the shutter -- what you'd normally do to find focus in AF mode -- is a useless action.
Additionally, do professional photographers use manual or autofocus? Yes. I use autofocus or manual focus most of the time. Generally I'll start out with some form of autofocus, then adjust the modes appropriately based on the type of subject and the scene. I'll switch to manual focus if autofocus doesn't “grab” focus properly or if autofocus is too slow.
Beside above, what is the difference between AF and MF mode?
Manual focus (MF) is the function to let the photographer adjust the focus manually instead of the camera. Although autofocus (AF) shooting is more typical in digital cameras, MF is effective when focusing is difficult with autofocus, such as in macro shooting.
When using manual focus What should the photographer do after moving the switch from AF to MF?
First, you need to switch your lens from autofocus to manual focus. You do that my moving the switch on the side of your lens from AF to MF (or A to M, depending on the lens). Next, bring the camera to your eye and frame the shot. Half-press the shutter button to acquire focus.
