A manual focus lens allows you to focus 100% manually, without the intervention of an automatic system. Before the introduction of the autofocus mode option, cameras could only be provided with the correct focus and settings by manual operation. Nowadays it is possible to switch to the manual function, indicated by MF, by a button on the camera. You can then use the focus ring to focus.
As a manual focus lens user retains full control over the image they wish to capture, this can be attuned to the environment, light incidence and distance to the subject with precision control. This is decisive in the definition you will capture your shot in. It is meticulous work but worth the effort, as an automatic focus may focus on the wrong subject area, giving you an unwanted result. Using present-day DSLR and mirrorless cameras it's not always that easy to attain the correct manual focus. Once you succeed, besides the feel-good factor, you also become more proficient on the workings of your camera and how to get the most out of your photo.
With macro photography precision focus is essential in attaining the limited depth of field ratio. As the subject to be projected is close to the photographer, it is hard to fully define the edges of the focal point using the autofocus function. Manually using the focus ring not only teaches you to precisely differentiate a subject from the background, but also how the autofocus works as well as its limitations. When photographing in low light, such as nocturnally, the autofocus often struggles to detect the correct focal point. Together with the live view mode on your camera and the right tripod, you can manually bring nocturnal subjects into better focus.
Manual focus lenses come in all shapes and sizes, primarily because manual focusing is a learning process and ensures quality improvement in your photos, whatever the situation. This, of course, depends entirely on the scenario in question, but both the wide-angle and telephoto lens offer this opportunity. In addition, lenses are available with either a fixed focal point or a zoom function. In the former, with manual focus it is important that you stand the precise distance away from your subject; in the latter, you must determine the manual focusing distance yourself using the zoom.
