单反相机在拍照片之前必须做的就是对焦，对焦的意思就是要让拍摄主体清晰，也有人叫合焦，只有对焦或合焦了，才能准确记录影像。传统相机对焦方式是转动对焦环，直到要拍摄的物体清晰，这叫手动对焦，不过现代单反相机常用的默认对焦方式是自动对焦了。今天我们就来讲讲单反相机如何手动精确对焦或是单反相机怎么才能做到手动精确对焦。
Before a SLR camera takes a picture, it must focus. Focusing means to make the subject clear. Some people call it focusing. Only when focusing or focusing can the image be accurately recorded. Traditional camera focusing mode is to rotate the focusing ring until the object to be photographed is clear, which is called manual focusing. However, the default focusing mode of modern SLR cameras is auto focusing. Today, we will talk about how to focus the SLR manually or how to focus the SLR accurately manually.
单反相机如何手动精确对焦
How to manually focus the SLR camera
手动对焦是通过手工转动对焦环来调节相机镜头从而使拍摄出来的照片清晰的一种对焦方式，这种方式很大程度上面依赖人眼对对焦屏上的影像的判别以及拍摄者的熟练程度甚至拍摄者的视力。准确对焦无疑是拍摄一张好照片的重要基础因素，但是因为我们拍摄的主体不同，主体的形态动态不同，所用对焦模式也不尽相同。选择合适的对焦模式更有利于我们拍摄成功。
Manual focusing is a kind of focusing mode that adjusts the camera lens by turning the focusing ring manually, so as to make the photos clear. This way largely depends on the human eye's judgment of the image on the focus screen, the proficiency of the photographer and even the photographer's vision. Accurate focusing is undoubtedly an important basic factor to take a good picture, but because of the different subjects we take, the dynamic shape of the main body is different, and the focusing mode used is not the same. Choosing the right focusing mode is more conducive to the success of our shooting.
我们将镜头的对焦模式开关设为手动对焦也就是MF，在取景器中显示放大框，在相机的背面，按下放大按钮，可以在相机屏幕上看到，局部放大图像，然后把放大框移动到想要精确对焦的位子，如果想让放大框返回中央，可以按下设置键或者删除键按钮，这样我们就可以对拍摄物体做精准的对焦了。
We set the focus mode switch of the lens to manual focus, that is MF, to display the magnifying box in the viewfinder. On the back of the camera, press the zoom in button to see the image on the camera screen, and zoom in locally. Then, move the zoom box to the position where you want to focus accurately. If you want to make the zoom box return to the center, you can press the set key or delete key button You can focus the object accurately.

还有一种情况下我们也可以用手动对焦，那就是我们用屏幕取景，在屏幕取景的模式下使用手动对焦一般都是使用三脚架，来防止相机因为抖动而造成的模糊景象。我们需要对被摄物的一小部分对焦，比如花朵的花蕊、人的眼睛进行对焦，我们可以使用三脚架，然后，通过放大倍数，来给花蕊或眼睛进行对焦。
There is another case that we can also use manual focusing, that is, we use screen view. When using manual focusing in screen view mode, we usually use a tripod to prevent blurred scenes caused by camera jitter. We need to focus on a small part of the subject, such as the stamen of a flower or the eye of a person. We can use a tripod and then focus the stamen or eye by magnification.
