以往,国产闪光灯除了价格低廉以外,很难找到什么亮点。但此次永诺用最新的568EX震撼了我们,它不仅支持TTL,还支持以往被国外闪光灯所垄断的高速同步功能。568EX到底有多强大?让我们拭目以待。高速壁垒一般来说,闪光灯同步的快门速度是1/250秒,而高于这个时间的快门时间,比如说1/640秒,则无法捕捉一瞬间的闪光。这是因为机械快门的本身限制造成的,在大部分相机上,快门能够全部打开的最快速度是1/250秒。当我们使用更高的快门速度时,相机的快门帘幕会采用开启一个狭缝扫过感光
In the past, domestic flash in addition to low prices, it is difficult to find what bright spots. But this Yong Connaught shocked us with the latest 568EX, which not only supports TTL, but also supports the high-speed synchronization features that were previously monopolized by foreign flash. 568EX in the end how powerful? Let us wait and see. High Speed Barriers In general, the shutter speed of the flash sync is 1/250 seconds, while shutter times higher than this, say 1/640 seconds, can not capture the flash of the moment. This is due to the limitations of the mechanical shutter itself, and on most cameras the fastest shutter speed can be 1/250 seconds. When we use a higher shutter speed, the camera’s shutter curtain will be used to open a slit sweep the light
