In pursuit of operability, shutter operation is improved so that the continuous focusing with half-shutter and shooting with full shutter is realized as is available in the system cameras.
在追求可操作性,改善,使连续对焦与半快门和全快门拍摄被理解为是在系统相机快门操作。
If you half click the shutter, your camera will read the light and place a line where it believes your exposure will be if you take the picture with your current Settings.
如果你半按快门,你的相机就会解读目前你所设定状态下的曝光情况。
Just like with f-stops, there is a mathematical relationship between different shutter speeds-each shutter speed stays open half as long as the one above it, or twice as long the one below it.
就和f值一样,这一组数字也是一个数列关系,每一档快门速度都是比上一档快一倍的时间,或者是慢一半的时间。
