Photographers are spoiled with a wealth of “automatic” features on today’s cameras. Autoexposure, auto white balance, and autofocus make taking a photograph as easy as pressing a button–without any intervention by the photographer. Naturally, this casual form of photography is totally dependent upon “ideal” conditions. In other words, ideal lighting, ideal composition, and ideal subject all lend themselves to leaving the camera configured with automatic settings.

Focus was easily shifted to the nozzle with manual focus.

Manufacturers know, however, that very few photographic situations are “ideal.” Therefore, automatic settings can be quickly and easily overridden by the photographer for achieving a desired image effect. One of the more visually powerful statements that is controllable by the photographer is focus.

Sure, you could move the camera and use focus lock to find these leaves, but manual focus allows you to compose your subject without any camera movement.

Selective focus is a mainstay in photography and both cameras and lenses, generally speaking, permit the disabling of autofocus. Whether via a switch or a menu setting, cameras and lenses can be toggled between autofocus and manual focus. There are some very curious outliers to this broad brushstroke characterization of focus. From the strictly manual focus camera to the widely unconventional autofocus camera, there’s something for every photographer and every photographic situation.

Focus on Your Composition

Nothing is more exasperating than watching the autofocus ratchet back-and-forth trying to locate the subject. While you patiently wait for the camera to automatically perform this photographer’s action for you, your subject could be gone. In situations like this, disabling the camera’s autofocus can not only put control back in your hands, but it can also ensure that the subject doesn’t escape your capture.

Most autofocus cameras have a hard time finding these pine needles, but manual focus enables you to “find” them with very little effort.

While it is deceptively easy to enable manual focus on today’s cameras, it only takes a little practice before you’ll develop an adept hand-eye coordination for selectively focusing on your subject. In fact, you might discover that manual focus is a more beneficial method for controlling this vital aspect of your photography. Armed with this newfound confidence in manually adjusting your camera’s focus, you’ll also discover an entire spectrum of manual-focus-only lenses that will now become viable options for outfitting your next lens purchase.

Enjoy.
