How does focusing with a camera work?

Focusing with your camera

How does focusing work with your camera? There are several settings you can use on your camera. Let's go through them:

 

AF method

Something you've used before, but how does it actually work? When taking a photo, we press the shutter release button of the camera halfway. We see through the viewfinder or on the screen, one or more dots light up and press the button further to take the photo.

Focusing is done in a fraction of a second. The speed of focusing also depends a bit on the camera and lens combination.

Focus point

Not the entire image is linked to the AF sensor, but only a few focus points. That varies from 11 to more than 500. You see these focus points as dots or zones in the viewfinder of the camera. The middle point is the most sensitive. This measures both the horizontal and vertical contrast with an extra high sensitivity, in less light or low contrast. You can purposefully select one focus point, but you can also use an entire zone.

Many photographers use the center focus point and reframe the image, then take the picture. You can also choose to choose a different focus point, but then you have to focus properly for each photo. There is also a mode where all focus points are active and the camera chooses a point itself. This is by far the fastest method, but can result in a photo where the wrong element in your photo is in focus.

One shot / Ai Focus / Ai Servo

With One Shot, the focus point is locked when the focus point is found. So this mode is ideal for shooting still subjects.

Ai Focus recognizes it when movement comes from a still image. It then tracks the moving subject to focus. If something accidentally passes by, it can be detrimental, because you don't want to focus on the moving subject at all.

Ai Servo is the ideal mode if you have continuously moving subjects that you want to focus on. For example, think of a sports competition or car races. The focus point then continues to move with your subject.

Auto focus in liveview
With newer cameras with a touchscreen, it is possible to tap your focus point on your LCD screen. In this way you are no longer tied to the number of focus points that you see through your viewfinder, but you simply tap the subject you want sharp in your photo.

Autofocus vs manual focus:

Your camera has trouble focusing automatically in the dark. The camera will not find a bright spot to focus on. This is not a disaster, because fortunately we can also focus manually. Also with macro photography you will often want to focus manually. So good to pay attention to!

If you focus manually, keep a few points in mind:

  • Turn off the image stabilization on your lens
  • First, determine a good composition and place your tripod in the desired location.
  • Set your desired aperture, shutter speed and ISO.
  • Always take a test photo first and judge if it is good.
  • Macro photography is all about details. So make sure you have good focus to make sure that the right element of your photo is in focus.
  • Use the infinity sign (see photo on the right) for the largest possible sharpness area. You can recognize the infinity sign by an 8-like symbol. Adjust to this and turn back a very small turn. How much exactly? That differs per lens. So just try it out.
  • Take your photo and check whether you have the desired sharpness.
  • After each photo taken, you have to manually focus again. Every change in composition or setting creates a new situation. So refocus.
To manually focus via your LCD screen:
  • All of the above points also apply to manual focusing via your LCD screen.
  • On your LCD screen you can see more clearly what your photo will look like and whether it is sharp.
  • You are looking for a bright light source on your LCD screen. This can be anything, a lamppost, an illuminated shop front, a shop window, you name it.
  • Zoom in on the light source with your magnifying glass and focus manually. You can clearly see when it is at its sharpest on your LCD screen.

Shooting with a tripod

Why is the tripod so important?

Tripod and ball head

Let's call it right, right away. This is one of the most important elements in photography. Your tripod is like your best friend! If you invest well in it, it won't let you down! So it's important to dwell on this for a moment.


Why is the tripod so important?

  • It gives stability.
  • You can take long exposure shots that you need for macro photography around twilight.
  • You reduse noise due to too high ISO values.
  • Without a tripod, no sparkling sharp photos.
  • The best results with focus stacking

What do you consider when buying? My tip, in any case, don't cut corners. Assume that you will once again purchase a new camera or lens and that your tripod must be able to carry it. Do you travel a lot? Then you would like a lightweight. Do you shoot a lot of macro? Then you want a tripod that comes close to the ground. For each type of photography, you can ask yourself what requirements your tripod must meet.

What questions you should definitely ask yourself:

  • What kind of photography do I use it for?
  • What is the total weight of my camera and lens? The heaviest version of course!
  • Do I want to expand in my lenses and what does my camera with lens weigh?
  • What requirements do I place on the tripod head?
  • When I go out, how much should the tripod weigh so I can take it comfortably with me?
  • What height should the tripod be?

  Tripod

There are various types of tripods on the market. You have very compact ones, such as a gorillapod and even a tripod on one leg, called a monopod. Feel free to research this on the internet. In general, however, we focus on the tripod, as this is the best variant.

The tripod stands firmly on three legs, as the name suggests. More expensive models are usually made of durable and sturdy materials. These tripods are very sturdy. Constant adjustment is also no problem for these tripods. They can be loaded more heavily. Pay attention to the weight of the tripod if you want to walk longer distances. You don't want to carry around too many pounds. Also think how big you are. It is pleasant to shoot when you have the camera at eye level on a tripod.

Remember: the heavier the weight, the more stable the tripod will be. Pay attention to the weight of the tripod if you want to walk longer distances. You don't want to carry around too many pounds.

Tripod head

A tripod head is available separately, which gives you flexibility. We discuss two types of tripod heads.

The most famous is the three-way head. You can move the three-way head in three ways: forward or backward, clockwise or counterclockwise, horizontally or vertically. This allows you to aim your camera extremely accurately. This can be done with levers, but also, for example, with rotary knobs where you can turn your tripod head per millimeter. three-way head

The second commonly used head is a ball head. It consists of a ball construction so that you can easily and quickly put your camera in the desired position with one lever. It is important with both models that the ball head must be able to bear the total weight of your camera and lens. Play it safe and rather add two kilos on top.

Other tips:

Some tips I don't want to withhold from you.

  • Cheap is expensive. It is a one-time purchase that you will enjoy for years to come.
  • Take good care of your tripod. This extends the lifespan.
  • Turn off the image stabilization on your lens. This ensures better sharpness.
  • In the camera menu, turn off noise reduction for slow shutter speeds. If necessary, you can apply this afterwards with editing.
  • Look closely at the environment. Placing your tripod a meter further can give a completely different perspective.
  • Make sure your tripod is stable and cannot tip over.
  • Cover the viewfinder to avoid unwanted rays of light.
