The whole setup with the Slider + Wizard Motion + Target is considered super light already …
I think its lighter than the Cinevate Atlas 10 i had previously (which is just a slider)
But actually, if you practice enough, you can do motorised-like motion day in day out … Non of the top pros has motorised sliders back in the days and their sliding shots are still awesome.
*of course, if you are talking about time-lapse, thats another thing. I had the dynamic perception machine and its hell big to bring around.
