Yes they do have a great built in flash, and I'm still using the cameras flash, it's just removed and separated to another housing. One of the big reasons guys want the flash away from the camera, is to get away from "eye glare" from the animals. For some reason, when the flash is mounted to the camera, that's when you get bad eye glare, and takes away from the picture. I believe someone here said, the flash needs to be at least 18" away from the camera, to get away from eye glare.
