In short, yes, it's a great combination for those who are focused on timelapse and travelling. You need any spectrum ST4 and one of our Geared Stepper motors and short motor extension cables. We recommend the 14:1 or 27:1 motors for inclined shots and the 5:1 motor if you are mostly interested in shooting level or very slight inclined shots.
eMotimo provides the motors only. From DP you will need a motor mounting bracket for this motor along with the belt, end clips, pulley, idlers etc that makes their system move!
Already have a motor from DP, or eMotimo from a prior version, reach out and open up a ticket with us. We might be able to save you some dough.
