Changing FOV. Correct, but Helicon Focus can handle this pretty well. In theory and with 100% centric lenses it's "only" magnification to be calculated".
Of course, the way you described - moving the lens only (like a bellows head) - is the best and possible with Manual focus lenses, but handling this procedure manually always has the risk of movinng the whole macro slide, or tripod, or tripod head if one is clumsy like me. ^_^ So, I prefer the "autopilot" method of Helicon remote. Or CamRanger, which can also make stacks, but less comfortable.
