But don't expect to use it to fire in rapid sequence, assuming that you'll be able to capture the full movement of the animal. Even at full speed, you'll still only catch a fraction of the animal's motion. And with moving animals, it's almost impossible to keep a sharp focus that long anyway. You can waste a lot of film shooting this way. We find that we rarely shoot more than two or three exposures at one time.
Some photographers feel that the motor drive's noise can scare the animals.
While this may be true to some extent, it hasn't been our experience. In some cases, though, such as when we're photographing songbirds up close, even the snap of the mirror is too much noise. While shooting birds nesting near our home, we have actually tried insulating the camera with foam and rubber bands to muffle the sound. But the best thing to do when your camera distracts the subject is to take a break and give your subject a chance to settle before beginning again. If your camera gives you the choice of interchangeable focusing screens, you may want to invest in a clear matte focusing screen for shooting wildlife.
