There's also a power button, shutter release, and zoom slider up top — all pretty standard stuff.
只买机身，然后另外购买一个高速镜头.（译者：一般指允许进光更多而提高快门速度的，大光圈镜头。
测算你相机的安全快门速度有一个好的方法，你相机镜头焦距的倒数，就是你避免镜头抖动的快门最小值。
A good rule of thumb to minimise camera shake is to set the shutter speed at a minimum of one second divided by your focal length.
实际上，当你按下快门时，一套复杂的程序开启，包括镜头内光圈的设置、一块单镜头反射镜的升起和其他更多的步骤。
When you press the shutter release on the camera, a complex sequence of events occurs, including setting the aperture in the lens, flipping up the mirror of an SLR and a lot more.
第一类是指将镜头对准天空，调校好，将焦距打开到“无穷大”，然后打开快门。
In the first case enough to aim the camera at the sky, fix it, set the focus "to infinity" and open the shutter.
用手机控制照相机的闪光灯、5倍变焦镜头和快门简直让人啼笑皆非，还要让手机给这些照片贴上地理标签，并且在手机上切换程序每次都会切断两者之间的连接。
It was a neat party trick to control the camera's flash, 5x zoom and with the phone -- and to have the phone geotag those pictures -- but switching apps on the phone disconnected the two every time.
就像镜头有一个光圈范围，你的相机也有一个快门速度的范围。
Just like a lens has a range of apertures, your camera has a range of shutter speeds.
你能保证这架相机的镜头和快门吗？
聚光镜装配有瞳孔膜，那是一个有贡杆控制的快门，用来调节进入镜头系统的光量。
The condenser is equipped with an iris diaphragm, a shutter controlled by a lever which is used to regulate the amount of light entering the lens system.
我之前也说过如果不是经济上的原因，我会使用f2.8尼康的镜头，因为其快门的速度比我现在的镜头快很多，而且清晰度也强。
As I have said before, if not for economic reasons, I would use my F2.8 Nikon lens because the shutter speed is much faster than my current lens, and it has strong clarity.
手持拍摄时，最低安全快门速度为所用镜头焦距的倒数，低于这一速度，相机震动可能导致照片的锐度下降。
Camera shake rule: The slowest shutter speed at which you can safely handhold a camera is one over the focal length of the lens in use.
