If you’re disappointed by Sony lack of an intervalometer in their new Sony a7RIII or a9 like I am than Meike’s pro grip from Amazon might be a good option for you. I was down in key west the other day shooting astrophotography with some friends and really missed the internal intervalometer feature on the Sony a7RIII, because time-lapse photography can be a lot of fun at night especially if you are waiting for a specific shot or if it is cloudy out.
