买数码相机要看哪些主要参数，怎么看？英文双语对照

相机是摄影的基础，所以买一台好相机，是非常非常重要的。以下就详细的说明一下，数码相机的一些参数及相应的选择要点

一、数码相机的种类

数码相机可分为可更换镜头相机和不可更换镜头相机两大类。其中不可更换镜头相机，我们又称之为卡片机，因为相对来说体积比较小，比如索尼的黑卡，是一个代表。

可更换镜头相机由于镜头是可以更换的，所以可以根据不同的拍摄对象和场景更换相应的镜头，有更灵活的组合方式。它又可以细分成微单、单反、中画幅相机等等。

因此，我们在选择相机的时候，要先分清这些大类，然后再做选择。

二、数码相机的成像单元

成像单元应该是数码相机的核心，它的尺寸，像素，支持的ISO范围（高感和低感），动态范围等，决定了一台相机的最重要的画质部分的精细度与呈现能力。

一般卡片机的成像单元尺寸都比较小，一般在1英寸以内。微单和单反，又分M43\APSC\全画幅等等尺寸。理论上来说，尺寸越大，成像质量越好。与之相应的还有一个总像素的参数。比如现在索尼的A7R4的像素达到了创纪录的6000万以上，那拍出来的相片，精度是非常大的，非常有利于后期的剪裁和大尺寸的输出。

三、数码相机的图像处理器

其实这是一个很容易被忽略的东西，就象电脑一样，CPU是核心，数码相机的图像处理器决定了图像的处理能力。越快的图像处理器，连拍速度越快，视频处理能力也越好。

四、对焦系统

这里面涉及对焦覆盖、对焦点的数量、最低照度可对焦、对焦时间等等参数，还包含人脸识别、眼部对焦等进阶功能。

五、视频能力

主要涉及是否能拍4k，1080p的升格能力，是否提供log调色功能等

六、防抖性能

机身的防抖能力在微单时代是比较重要的。

七、重量体积

这个应该是大家都很关注的点了，包括握持感等，这些最好还是到实体店亲自体验下比较好。

八、专业特性

连拍速度、是否具备双卡槽、电池容量、取景器的视野率和放大倍数、是否能够防尘防滴、按键是否能够自定义、有没有配套手柄、镜头的卡口与支持等等。

以上就是购买数码相机要注意的一些参数要点了，更详细的资料，可以关注我的头条号，里面有很多关于选购相机的内容。

Camera is the foundation of photography, buy a good watch for a chance so, it is very special and important. The following with respect to the expatiation, a few parameter of digital camera and corresponding choice want a place

One, the sort of digital camera

Digital camera can be divided to can change camera lens camera is mixed cannot change camera lens camera two kinds big. Cannot change among them camera lens camera, we say again for card machine, because opposite for volume is minorrer, for instance black card of Suo Ni, it is a delegate.

Can change camera lens camera because camera lens can change, can film according to what differ object and setting change so corresponding camera lens, have more agile combination. It can Cheng Wei sheet, sheet turns over fractionize, in picture camera is waited a moment.

Accordingly, when we are choosing camera, want kinds big to distinguish these first, next redo choice.

2, of digital camera into resemble unit

Into the core that resembling unit should be digital camera, its dimension, resemble element, ISO limits of support (tall feeling and small move) , dynamic limits, the essence of the most important picture qualitative part that decided a camera is fineness with present capacity.

Of average card machine into smaller like unit dimension, be in commonly 1 inch of less than. Small sheet and sheet are turned over, divide M43\APSC\ full frame to wait dimension a moment again. Theoretic for, size is larger, it is better like quality to become. Return the parameter that one always resembles element accordingly to it. All alone now for instance of the A7R4 of the Buddhist nun achieved record-breaking 60 million above like element, the photo that takes then, precision is very big, special the output of the clipping that is helpful for later period and large size.

3, the image processor of digital camera

Actually this is a very easy uncared-for thing, like be just like computer, CPU is core, the image processor of digital camera decided the processing capability of image. Jump over fast image processor, take rate repeatedly faster, video handles ability to also had been jumped over.

4, to anxious system

Involve inside this right anxious enclothe, intensity of illumination of the amount to the focus, lowest can is opposite anxious, right parameter is waited a moment between Jiao Shi, still include a person ministry of facial identifying, eye is right anxious etc into rank function.

5, video capability

Basically involve whether can pat 4k, the promote ability of 1080p, whether to offer function of Log mix colors to wait

6, prevent shake function

Of airframe prevent shake ability to be in small only period is more important.

7, weight volume

This should be the dot that everybody pays close attention to very much, include to grasp hold feeling, these still had better arrive hypostatic store has been compared below the experience personally.

8, professional character

Take the speed, view that whether has capacity of double card chamfer, batteries, viewfinder repeatedly rate and enlarge multiple, whether can whether can be dustproof protected against dropping water, key-press defined oneself, the card opening that has handle of form a complete set, scene and support are waited a moment.

Above purchases the point of a few parameter that digital photograph confidential notes namely, more detailed data, the head that can pay close attention to me date, there are a lot of contents about camera of choose and buy inside.
