Camera Manual Focus and AutoFocus

All lenses for dSLRs have the capability to toggle between manual focus and autofocus modes. While you can use manual focus for literally any situation, autofocus can be a great asset for saving time. The debate on whether to use manual focus or auto focus with your dSLR should be assessed on a case-by-case basis.

When a lens is set for autofocus mode, it utilizes a detection system to automatically adjust the lens until your subject is in focus. The primary benefit of using autofocus is its quickness in adjusting the lens accurately. Autofocus is a great utility for candid photographs or any other scenario in which your subject may be moving around. Additionally, many cameras have an autofocus function for continuous focusing when a subject is in motion. As you track the subject with your camera, continuous focusing automatically adjusts the focus as the subject gets closer or further away so you don't have to repeatedly change the focus yourself. One caution for using autofocus is that while using this mode, the camera will not take a picture if the lens is out of focus. Autofocus does have some limitations, however, that can be circumvented with the use of manual focus.

Theoretically, you can use manual focus for any scenario. It may take a moment or two more to focus the lens, but practice can quicken your abilities to manually adjust the focus. Once you're comfortable with manual focus, it can be used to overcome some of the problems you may experience when using autofocus. If autofocus has difficulty in determining the subject of your photograph and cannot focus properly, it may slow down the camera from releasing the shutter if not prevent the shutter release altogether. The benefit (hopefully) of using manual mode is that, regardless of your subject being in focus, you will always be able to take the picture. One scenario in which you may experience this trouble with autofocus is if there is not enough light for the camera to assess your subject. The camera will not be able to detect enough contrast to evaluate the image and you'll notice your camera extending to the full focal length and then retracting. Using manual mode will allow you to focus on your subject quickly and avoid any missed opportunities caused by the camera's confusion in autofocus.
