I thought about taking motors with steps as little as 1.5 degrees or half but they are very expensive + I do not know if such a motor could be strong enough to drive the camera with a low ratio gear box and light weight....... I am still stuck with the max steps/s. I really have to take down each motor specs and calculate the gear for best torque/speed ratio. It's tricky :o) !
Sometimes I think I'm real nut trying to realize my dream !
