In the previous lesson, we talked about how to let the camera decide where to put the plane of focus. However, there are many situations where you might want to take over that important task and do it yourself.
The only practical way of focusing manually is via a ring on the lens. Sadly, manufacturers still haven’t agreed on which of the zoom or focus ring should be closer to the photographer, so there is no general rule, but those two rings should be found on any modern zoom lens. Most lenses and cameras require you to flip a physical switch to alternate between AF and MF. Some modern lenses also offer a very useful M/A mode: autofocus is used normally, but you can turn the manual focus ring at any point to override the camera and take control.
To achieve correct focus, you need a way of evaluating accurately how sharp your subject is. This means that you need to have a viewfinder large enough that small differences in focus will show. Sadly, most entry level DSLRs have tiny viewfinders, and this is one place where higher end bodies will make a clear difference. If you frame with liveview or an electronic viewfinder, you can often ask the camera to magnify the central area, thus allowing very precise focusing, the downside being the slowness of the whole process.
Even when you are in MF mode, the AF sensor will remain active and give you focus information. Just like the light meter tells you when it thinks you have achieved a good exposure in manual mode but lets you decide what to do with that information, the AF sensor will tell you when it thinks you have a well focused image, usually via means of a dot appearing in the viewfinder. Of course, you probably shouldn’t trust it entirely (if you do, save yourself the trouble and go back to autofocus), but it is still useful information to have.
It can make sense to use manual focus in the following situations:
In the last photo with the girl and the mountain. The girl is not focused very precisely. The face, hands, and shoes reveal a lack of sharpness/detail.
Is this on purpose? Is the Plane of Focus set on the mountain instead?
