How to focus accurately when focusing manually

Lead: Nowadays, digital SLR cameras have powerful auto-focusing function, but there is still room for manual focusing. In fact, manual focusing is more convenient in the case of dark light or low contrast of the subject. Manual focusing is the fastest way to take macro photos. Here are some common skills to improve your success rate of manual focusing.

In autofocus, the lens will focus on the focus according to the photographer's choice, but the focus locked by the camera may still have a certain gap with the clearest part you want. Especially when taking macro photos, the depth of field is extremely small, and the subject should be completely focused. At this time, you need the manual focusing or full-time manual focusing function of the lens, that is, after the lens is focused, manually adjust the focus ring and accurately adjust the focal length.

Manual focusing is also useful when shooting outdoors. For example, if you want to shoot the reflection of the water surface, autofocus usually focuses on the water surface itself. The same is true of taking pictures through the glass. At this time, backward focusing is better than pressing the shutter once and a half? Take a chance? Much more effective.

▲ When taking macro photos, manual focusing is much faster and more accurate than automatic focusing. Of course, you need to practice hard.

How to make each photo focus accurately?

1, adjust diopter

If the diopter of the viewfinder is not accurate enough, manual focusing will not be accurate. Keep your eyes on the viewfinder while rotating or sliding the diopter adjustment controller next to the viewfinder to clearly adjust the image when focusing. On different models of cameras, the setting method is different.

Step 2 use the focus ring

The use of the focus ring is also skillful. There is a distance mark on the focus ring, which can help you focus accurately when shooting in dark light. When focusing, twist the focusing ring back and forth near the focus to narrow the range a little and then determine the focus. This process needs more practice at ordinary times.

3. On-site inspection

When shooting still life, you have plenty of time to focus. At this time, you can turn on the live view function, enlarge the focal length, and then fine-tune it with the focus ring. Especially when shooting macro, the focal difference of 1 mm may waste the whole picture, so be sure to focus carefully.
