One of the most challenging aspects of switching from a compact camera to a digital single lens reflex (DSLR) is learning when to switch from autofocus to manual focus. A photographer today can choose from a wide variety of Automatic and Semi-Automatic shooting modes available on their digital camera. Most of these have to do with adjusting the exposure of your photos, but many cameras also offer a variety of focusing modes (e.g., auto, continuous focusing for moving subjects, single-point focusing, multiple points focusing, face recognition focusing, etc. manual).

It's no wonder then that many photographers never use their camera and lens' ability to focus manually. So, when is manual focus better than autofocus?
FAQs About Photography
DSLR Autofocus vs. Manual Focus
Before anything else:
Where do autofocus and manual focus differ? To put it briefly, autofocus works by having the camera determine where the emphasis should be in the image. On the other hand, a manual guide will help you focus on the right things because you'll get to decide how effective that focus is.
That is to say
If your camera has autofocus, it will take care of focusing for you and produce sharp images every time. If you want to get a quick shot, manual focus is the way to go because you control the direction and the focus.
Even with autofocus, however, you will still need to put in some effort, so this may be a simplification. Setting the AF point, if at all, is still a discretionary option, for instance.

Manual Focus Vs Autofocus: Which One Is Better?
The advantages and disadvantages of each focusing mode should be considered when deciding which one is best for your photography.
- Allows for more precise adjustment of the focus before firing.
- Enhances focusing precision.
- The optimal focus is chosen by the camera.
- It's much quicker than following the instructions in a book.
- Camera models can make a difference in image quality.
Both autofocus and manual focus accomplish the same goals. Each can be used to change the angle of view of the camera. However, autofocus allows the camera to automatically determine the optimal focus by utilising a variety of specialised sensors. When using autofocus, the photographer is relieved of all responsibility.
Manually, the photographer must adjust the lens focus by hand. While both can produce great results in most circumstances, there are times when it's better to choose one over the other. Choosing the right wedding photographer in Melbourne to capture every moment on your wedding day.
Autofocus Pros and Cons
Although autofocus is typically very quick, it can vary greatly depending on the camera and lens you're using. Cameras and lenses designed for landscape photography are typically much slower at focusing than those designed for sports and other action photography.
In addition, tracking is one of the more intriguing recent developments in autofocus. Set the focus on the subject of your shot, and the camera will follow it as it moves around the frame. It stands to reason that AF tracking is ideal for capturing fast-moving subjects like birds in flight, animals in pursuit, or athletes in action.
Technology like Eye AF has been added to more modern autofocus systems, allowing the camera to quickly lock onto the subject's eyes (typically human, but occasionally animal).
- It happens mechanically, automatically.
- Compared to manual focus, this method is much quicker.
- Intended for use with subjects that are in motion.
- To put it simply, it's perfect for newcomers.
While autofocus is usually reliable, there are instances when it won't lock on. In particular, autofocus systems rely on contrast to identify subjects; when that contrast is lost, so is the ability of the AF system to lock onto a moving object.
Since there isn't much of a contrast when shooting in strong backlight, autofocus systems will inevitably struggle. Furthermore, AF systems struggle in dim conditions because the camera needs to see in order to determine where to focus. Although autofocus systems have improved, there will come a time when every lens is out of focus regardless of the system (though this can vary significantly from camera to camera).
Third, autofocus struggles when there are many objects in the scene; it is easily distracted by foreground objects when you might want to grab focus on something in the middle ground or background. For instance, it can be difficult to concentrate during a snowstorm. When shooting in snow, the autofocus system becomes distracted by the falling snow and has trouble maintaining focus.
When it comes to accuracy, autofocus is a weakness, which brings us to point number four. To quickly focus on a distant object, autofocus allows you to zoom in on the subject automatically. In landscape photography, for example, where you want to repeatedly focus on a specific (hyperfocal) distance, or portrait photography, where you want to focus on the subject's nearest eye, this is a problem.
- If you don't prefocus, shutter lag may result.
- The possibility exists that you are concentrating on the wrong aspect of your topic.
- A lot less accurate than focusing by hand.
Lastly, when shooting at a high magnification, autofocus becomes increasingly difficult to use. When using a macro lens on a close subject, autofocus can be extremely frustrating, to the point where many photographers simply give up.
For the most part, autofocus is much more convenient than manually adjusting the focus. Also, it has a faster subject acquisition rate. For this reason, it is ideal for shooting subjects that are in motion. The subject you're trying to photograph may only give you a few seconds of your time if you're doing street photography. If you have to focus manually, your subject may have moved by the time you snap the shot.
The autofocus is quick, but it does have a slight delay. The time required for the focusing motor to function is significant. That is something to keep in mind at all times, but especially when shooting action.
Not that we think manual focus is hopeless for shooting sports or other fast-paced subjects. The best way to use a manual guide when shooting moving subjects is to prefocus on the area where you anticipate the residents to enter.
Different DSLR models will offer a variety of autofocus modes, such as:
- Because focus locks at the halfway point of the shutter release, AF-S (single-servo) is best used for shooting still subjects.
- The autofocus in AF-C (continuous-servo) automatically shifts to follow a moving subject.
- When activated, AF-A (auto-servo) allows the camera to decide between two autofocus modes.
- When the issue is partially in bright sun and partly in shadows, autofocus has a tendency to have problems working correctly when the subject and background are similar. There's a barrier in the way of the camera's view of the subject. Turn to manual focus mode in those cases.
Autofocus generally causes the camera to zero in on whatever is dead centre in the frame. Yet, the focus point can be adjusted on the majority of DSLR cameras. Choose the autofocus area option and use the arrow keys to reposition the focus.
Labeling the camera lens with a M (manual) and an A (autofocus) indicates the presence of a focus mode switch (auto). M/A mode, which is autofocus with a manual focus override option, is available on some lenses.
In most cases, shutter lag is not an issue when using a DSLR camera; however, the quality of your autofocus mechanism can affect this.
If you use autofocus and prefocus on the scene, you can avoid shutter lag. To focus automatically, press the shutter button halfway and hold it there until the camera focuses. The final step in taking a photograph is to fully depress the shutter release button. The delay when the shutter releases needs to be fixed.
Manual Focus Pros and Cons
When you focus manually, you can pick your focus point with great accuracy, even in a chaotic scene.
Manual focusing is preferable to autofocus in challenging conditions. Your eyes serve as the focus points (and they do a much better job of it than your camera's AF system!).
- Basically, it lets you zero in on your target with greater accuracy.
- Ideal for close-ups and portraits.
- A marked improvement for low-light photography.
As a rule, manual focus is much slower than autofocus, though there are some notable exceptions.
Therefore, manual focus fails miserably in situations involving motion, like shooting birds in flight or capturing athletes in motion. In addition, the manual instructs photographers to pick their own focus point.
When shooting from the hip, for example, it's often fine, but there are times when you want to fire but can't see to focus manually (e.g., you have your camera hung around your neck or held at your waist while you fire off some shots).
You can always prefocus manually if you want to. However, that isn't always the best strategy, particularly if you want to achieve a shallow depth of field effect.
- Comparatively slower than autofocus.
- It's difficult to capture moving subjects.
The use of manual mode is often prefered by professionals. This is so because it allows for greater precision when setting the focus for a shot. When the subject isn't moving around too much, manual focus is your best bet. In low-light, portrait, and macro photography, this is especially important to keep in mind. It is possible that your camera's autofocus setting will lock onto the wrong part of your subject, ruining your shot.
When using manual focus, cup the lens in the palm of your left hand. Then, using your left fingers, give the focus ring a gentle twist until the image is in focus. When shooting in manual mode, a steady hand is essential.
Otherwise, it will be awkward to support the camera while using the manual focus ring. This may make it challenging to shoot the photo without a slight blur from camera shake. We have the best wedding photographer in Yarra Valley to capture your beautiful moments on your wedding day.
When is Manual Focus Better than Auto Focus?
We want to preface this by saying that there is no "wrong" time to use manual or autofocusing; both can yield excellent results in the vast majority of situations. However, there are a few instances in which switching to manual focusing may prove to be more convenient. Among them are:
Because of the shallow depth of field, even the slightest focusing error or accidental focus on the wrong part of the subject can ruin the shot (for better or for worse).
Taking your photography into your own hands, manual focusing ensures that only the elements you want are in focus.
Macro photography entails getting very close to the subject in order to capture details that would otherwise be lost. Taking a close-up picture of a bug's eye is an example of macro photography.
Unfortunately, many camera lenses have trouble focusing on the subject when it is very close to the lens when using auto-focus. As a result, you may experience lock-on problems like your lens jerkily switching the focus point back and forth or missed focus, in which your lens focuses on the wrong subject.
Accurate focus is essential when shooting portraits. You'll want your subjects' eyes to be looking in the right direction for the vast majority of your shots.
Instead of having to prefocus on the eyes by pressing the shutter button halfway, switching to manual focus will give you full control to make this possible.
Shooting Through Glass or Wire Fences
If you've ever tried to take a picture through a window or a mesh/wire fence at a zoo or museum, you know that cameras have a hard time figuring out what to focus on.
It's easy to get distracted and start staring at the fence or glass instead of where you want your focus to be. By switching to manual focus, you can prevent this from happening and instead tell the camera what should be in sharp focus and what should be blurred.
It can be frustrating to use autofocus on subjects that are moving quickly (such as racing cars, planes, running or flying animals, etc.).
If you don't pan smoothly with your subject, even the continuous focusing modes can get lost or confused. Switching to manual focus and shooting at a point where you anticipate the problem to be resolved is one strategy for dealing with this.
When shooting in low light, manual mode is your best bet.
To put it plainly, there are benefits to switching to manual focus. Consider taking pictures with a DSLR while in Live View mode. In most cases, the image will be sufficiently magnified on your screen or viewfinder to allow you to make the idea as crisp as you like.
Autofocus has its drawbacks in low-light situations because it needs a certain amount of light and contrast to function properly.
Focusing can be tricky for some cameras and lenses when shooting in low light.
When your camera is having trouble focusing in Auto mode, you can tell because the lens will constantly spin from one extreme to the other before settling on a focus point. This can slow you down during shoots and make it difficult to capture spontaneous moments.
Planning your dream wedding and don’t want to miss out on the special moments on your big day? Worry no more, Wild Romantic Photography has you covered.
Landscape photography is a popular subgenre of photography, so it may come as a surprise that some people are unsure whether to shoot in manual or auto mode. One would think that by now everyone would be on the same page.
Because autofocus can be unpredictable, it's best to switch to manual focus when shooting landscapes.
When shooting landscapes with a manual lens, keep in mind that you'll need to take things much more slowly. There is a significant upside to taking a more methodical approach to landscape photography, though: setting the focus at the ideal distance to achieve the desired depth of field.
You can take as many landscape photos as you like without worrying about running out of light. In contrast to shooting action or sports, landscapes require you to be in one place for extended periods of time while you camp out to get the perfect shot. This works in your favour because you'll have to take your time getting the focus and composition just right.
When is Auto Focus Better than Manual Focus?
Manual focus has its advantages and disadvantages in photography, just as autofocus does. However, the real challenge lies in knowing when to use each strategy.
Knowledge of when one type of focus is more appropriate than another is a hallmark of any competent photographer. The more professional experience you have, the more natural this will become. At Wild Romantic, we have the best wedding photographer in Mornington Peninsula to capture every single moment on your wedding day.
With the advent of autofocus, taking clear photographs of birds in their natural habitat has become a breeze, making autofocus a welcome companion for all the bird watchers and photographers out there.
Use autofocus when shooting action or sports, where subjects often change direction quickly. If the subject is moving towards or away from the camera, selecting continuous autofocus mode will allow the camera to maintain sharp focus.
Photography, at its core, entails the generation of static visual content. Promotional photography is commonly used for the purpose of advertising a movie or television show. Taking pictures of inanimate objects (like a lamp!) is not the same thing as still life photography.
How Do I Know Which Focus I'm Using?
Pressing the DSLR's "Info" button will display the camera's current focus mode. The camera's LCD screen needs to show the current focus mode in addition to the other options. The focus mode setting might be displayed using an icon or initials AF or MF. Verify your familiarity with these symbols and abbreviations. If you need help with your DSLR, you should probably consult the manual.
It is common for interchangeable lenses to have a switch that allows you to toggle between autofocus and manual focus.
Which Should I Choose?
Use autofocus mode while you learn your camera's controls and practise improving your composition and lighting if you're just starting out as a photographer. The manual mode of your firearm's trigger should also be mastered, though. A better understanding of the advantages and disadvantages of each will help you develop as a photographer and expand your creative options.
