Thank you
The Helicon FB Tube (Canon and Nikon only) is $199 and has an internal chip (app for laptop (PC&Mac), smart phone or tablet to control it). You set the camera and lens combo, pick the settings and pick a # of frames, the tube controls the lens and changes focus for each frame while shooting on burst. Instructions are a bit sketchy but I am gradually learning it.
Thanks for the info, Robert.
