the body doesn't control settings for time lapse stuff. also, the shutter is only good for 30" unless you have a remote. And even when you do have a remote, you still have to time it with s stopwatch or someting else. but with the utility you can time it in bulb to whatever you want and when the timer is up it will close the shutter.
Time elapse? You mean a pic every few seconds or minutes automatically?!!
