内闪就是相机自带的闪光灯吧，英语是build-in flash or internal flash？
TTL (Through The Lens) flash technology in 1980. The basics of TTL operation is rather simple and applies to all camera systems. With TTL flash exposure, when the shutter is tripped, the light from the flash fires off, racing to hit the subject. This light hits the subject then bounces back to the camera. The light traveling the speed of light, travels through the lens (and any filters which may be attached) and strikes the film plane. The light then bounces down off the film to a sensor which reads the light as it builds up exposure on the film. Once the sensor and the connected computer software determines the light has massed enough for the correct exposure, the camera's computer turns off the flash (just like a light switch in a house goes on-off).

内闪的局限性太大，买外闪吧。580太贵，430也不错啊，或者sigma的super DG500，你会发现有很大的不同，特别是fill flash.
