打个比方，通过电子取景器，在拍摄前，你可以看到按下快门后的出片效果(白平衡，曝光，对焦等等)。
For example, you can see exactly what effect your Settings will have before you take the shot (white balance, exposure, focus, and so on).
比较可能的功能有电子罗盘，处理器和内存升级，具有自动对焦和拍摄视频功能的摄像头，和其他一些小的升级。
Likely features include a digital compass, processor and memory upgrades, an improved digital camera with auto-focus and video-recording capabilities, and other minor improvements.
传统上，数码单反相机使用一个单独的对焦感应器进行相位侦测。
Traditionally, phase detection in DSLRs has been conducted by a dedicated AF sensor.
夜景不便自动对焦，因为没有足够的光线或者鲜明的对比，而若手动对焦，取景器亮度又不够，这些使得夜间摄影的对焦更为复杂。
To further complicate focusing, night scenes rarely have enough light or contrast to perform auto focus, nor enough viewfinder brightness to manually focus.
如果您使用的是自动对焦相机，您需要先锁定焦点，这是因为大多数相机将焦点对准取景器中心的物体。
You'll need to lock the focus if you have an auto-focus camera because most of them focus on whatever is in the center of the viewfinder. Try it yourself.
f制光圈(或称光圈)决定相机的景深(对焦区域)以及有多少光能通过镜头到达传感器。
The f-stop, otherwise known as the aperture, determines your depth of field (the area in focus) and how much light can pass through the lens to reach the sensor.
当您使用红外线胶卷和红外线滤光器时，请您必须经常调整您的焦距至红外线对焦标记。
Always readjust your focus to the infrared focusing mark when using infrared films and infrared.

取景器图像对镜头精确对焦是非常重要的，它将影响图像的清晰度。拍摄不同用途的照片常常需要不同的对焦屏。
The viewfinder image is crucial for accurate focusing of the lens, and therefore greatly influences image sharpness. Different photographic applications often require different focusing screens.
当相机的AF - ON按钮按下后显示屏关闭并且可以用多选择器选择对焦区域。
When the camera's AF-ON button is pressed, the monitor turns off and a focus point can now be selected using the multi selector.

本文详细研究了一种基于FPGA和CCD图像传感器的自动对焦系统。
In this paper, we researched an Auto-focus system which is based on FPGA and CCD image sensor.
采用分区耦合的计算方法，实现了对工业焦化炉从燃烧器、炉膛、炉管整体几何结构的仿真，并且对焦化炉内流动、燃烧和传热全部工艺过程进行了模拟。
The whole geometric structures of combustor, combustion chamber and furnace tube in delayed coking furnace were accurately calculated by the whole-coupling method.
一种影像撷取装置，其包括：一个镜头、一个影像感测器、一个对焦单元、一个闪光灯及一个闪光灯控制单元。
An image capturing device includes a lens, an image sensor, a focusing unit, a flashlight and a flashlight control unit.
此镜及以后的版本可对焦到28英寸，这是继DR之后50mm取景器对焦的最近距离。
This and later versions focused to 28, the closest focusing RF coupled 50 after the DR.
修正了竖直拍摄时自动对焦点在取景器中的显示问题；
Fixes the AF point display for the viewfinder electronic level when shooting in the vertical position.
