Focus zoom from eMotimo on Vimeo.
4-axis move tests with the eMotimo spectrumST4 and two Fz motors – pan, tilt, focus, and zoom all controlled simultaneously with the wireless gaming controller.
The eMotimo spectrum st4 is a 4-axis motion controller with pan and tilt built-in. It is meant for cameras 15 lbs and lower. It integrates and drives 2 additional powered axis like slide and focus. It is controlled by either the included wireless gaming remote, or the navigation joystick on the side of the unit.
For this video, the eMotimo spectrum st4 was paired to an iFootage Shark S1 slider in the above video enabling 3 axis (pan,tilt,slide). You can find more information about this slider or purchase the bundle.
