Manual focus is something that I have a feeling a lot of people know about or don't have a good option for, but I feel like it is worth posting about, because it is something that I will probably go into more depth on in my blog here.

The most important thing to note is that Manual focus (MF) isn't available for all cameras, especially not phone based cameras. It is available on some point and shoot cameras, though not easily used in most cases, so it may be worth looking in your manual or googling to see whether your camera model supports any good implementations of MF. The most common place to use manual focus is on DSLRs (digital single lens reflex) or EVILs (electronic viewfinder with interchangeable lens), which are usually built to allow the user to easily control most elements of the camera's operations.
