Thanks! A lot to consider. I appreciate all of your information!

I'm practicing shooting the upcoming April solar eclipse and I need to use the interval timer to shoot the sun over the four minutes duration of totality. It seems the interval timer can only be started by pressing the Menu/Ok button, not using the cable. (It does allow a minute (or more) delay start but that's too much time wasted when eclipse totality is only four minutes!) When I start the interval timer immediately, there is significant camera shake that ruins the first set of images (I'm also bracketing) with the 560mm focal length I am using. I suspect there's no good answer, but is there any way to start an interval timer immediately without touching the camera? Thanks.
