50mm被称为标准镜头。有这么多的表达式为50mm头，你可以从名称“标准”，焦距是不寻常的。50mm以上用于人文、人像拍摄。类似于人眼的透视，适合人文拍摄。同时还具有很好的背景模糊效果，适合拍摄人像。还有主镜的焦距。
50mm is called standard lens. There are so many expressions for 50 mm head that you can get from the name "standard", focal length is unusual. More than 50mm is used for Humanities and portrait shooting. Similar to the perspective of human eyes, suitable for Humanistic shooting. At the same time, it also has a good background blur effect, which is suitable for portrait shooting. And the focal length of the main mirror.
肖像镜头
Portrait lens
85毫米被称为人像镜头。可以有很好的背景模糊效果，很好的图片切割能力，还可以保持适当的模型之间的通信距离。事实上，很多的焦距都可以用来拍摄人像，当然，85毫米的人像，特别是特写是非常好的。这也可能是因为85毫米相机除了拍摄肖像照外，其他效果都不是很好。这叫肖像照。
85 mm is called the portrait lens. It can have a good background blur effect, a good image cutting ability, and also can maintain the appropriate communication distance between models. In fact, a lot of focal length can be used to shoot portraits. Of course, 85mm portraits, especially close ups, are very good. This may also be because the 85 mm camera is not very good except for portraits. This is called portrait.
超广角变焦镜头
ultra wide lens
指11mm、12mm、14mm、16mm、18mm等超广角变焦距，24mm、35mm等截焦距。可以实现从超广角到一般广角的不同焦距。
It refers to 11mm, 12mm, 14mm, 16mm, 18mm and other ultra wide angle zoom, 24mm, 35mm and other sectional focal length. It can realize different focal lengths from super wide angle to general wide angle.
标准变焦镜头
standard zoom lens
它一般是24毫米或28毫米起飞，70毫米，85毫米，120毫米左右切断。基本上是一张你挂起来的照片。两个最常见的主题，风景和肖像，是覆盖。
It usually takes off 24 mm or 28 mm, 70 mm, 85 mm, 120 mm or so. It's basically a picture you hang up. Two of the most common themes, landscape and portrait, are coverage.
长焦镜头
Telephoto lens
200毫米和300毫米，这是一个很好的远摄，射鸟，荷花，体育，那些不是太远。所以它也被称为远摄或远摄。用来拍摄远处的物体。
200 mm and 300 mm, it's a good telephoto, shooting birds, lotus, sports, those are not too far away. So it's also called telephoto or telephoto. Used to photograph distant objects.
超快的镜头
Super fast shot
300多毫米镜头，适合野生动物、运动等。它也被用来拍狗仔队的照片。拍摄日出和日落，满月和一切。属于远摄镜头还是无法触及，需要超远摄镜头的帮助。
More than 300 mm lens, suitable for wildlife, sports, etc. It's also used to take pictures of paparazzi. Shoot sunrise and sunset, full moon and everything. Belong to telephoto lens or can not touch, need the help of telephoto lens.
中长变焦镜头
Medium length zoom lens
指起跳70mm、100mm左右，直到200mm、300mm、400mm截止。适合肖像，以及一些遥远的主题。
It means to take off about 70mm and 100mm until it is 200mm, 300mm and 400mm. Suitable for portraits, as well as some distant themes.
超长变焦镜头
Ultra long zoom lens
指镜头150mm、200mm跳跃，直到500mm、600mm停止。这种镜头适合远摄。
It means the lens jumps 150 mm and 200 mm until it stops at 500 mm and 600 mm. This kind of lens is suitable for telephoto.
了解了这些之后，是不是以后拍风景的时候一定要16mm, 24mm，这样拍人像一定要50mm还是85mm?当然不是。太教条了。
After understanding these, is it necessary to shoot 16mm and 24mm landscapes in the future, so as to take a portrait of 50mm or 85mm? Of course not. It's too dogmatic.
事实上，不同的焦距给了我们不同的视距。得到正确的范围，你不需要关心你使用的焦距。它可以是一个整数，比如24mm、35mm、50mm，或者是一个奇怪的焦距，比如41mm。只要范围合适。
In fact, different focal lengths give us different sight distances. To get the right range, you don't need to care about the focal length you use. It can be an integer, such as 24mm, 35mm, 50mm, or a strange focal length, such as 41mm. As long as the scope is appropriate.
另一方面，这并不意味着风景摄影必须使用广角，肖像摄影必须使用中焦距。其实在很多大场景中，远摄拍摄的场景也很不错。或者广角照片也不错。焦距和物体之间的关系并不是绝对的
On the other hand, this does not mean that landscape photography must use wide-angle, portrait photography must use medium focal length. In fact, in many big scenes, the telephoto scenes are also very good. Or wide-angle photos. The relationship between focal length and object is not absolute
但是我们仍然需要理解焦点和主题之间的关系。这是一个概率问题。当我们把世界各地的风景照片放在一起，你会发现有很多广角镜头。拍下50mm镜头的所有照片并计数。这就好像人类和肖像照片占了很大的比例。
But we still need to understand the relationship between focus and theme. This is a question of probability. When we put together landscape photos from all over the world, you will find that there are many wide-angle lenses. Take all photos of 50mm lens and count. It's as if humans and portraits account for a large proportion.
虽然每个人都有自己不同的习惯，但是如果你是一个风景摄影爱好者，却没有广角镜头，或者是一个顶级的专家，或者真的什么都不知道。
Although everyone has different habits, if you are a landscape photographer, you don't have a wide-angle lens, or a top-level expert, or really don't know anything.
