Affordable DIY Focus/Zoom Motor for Motion Control

Indosnews: Affordable DIY Focus/Zoom Motor for Motion Control

In an innovative move for camera enthusiasts and filmmakers, a DIY geared stepper focus or zoom motor has been developed, offering an affordable solution for motion control, follow focus, and other camera automation needs. This custom-built motor system is based on standard 0.8 module gears and attaches to 15mm rods, commonly found in motion control rigs, making it accessible for various setups.

Weighing only 135g and costing about 10€ to build, this motor utilizes a 12V bipolar stepper motor, making it an ideal choice for hobbyists, content creators, and aspiring filmmakers who want to experiment with focus or zoom motion control without a hefty investment. The system is compatible with off-the-shelf motion control setups, providing a straightforward entry into automated camera movements.

One of the standout features of this motor is its cost-effective design. The system uses 3D-printed bevel gears, which help to keep production costs down. While these 3D-printed components may affect the longevity and accuracy of the system, users have reported good repeatable results, making it a viable option for testing and light use.

The lens type plays a significant role in the performance of the system. Cinema lenses with a greater focus throw and smoother focus ring movement yield better results. However, the system has also produced decent results with more standard lenses, like the Canon EF-S kit lens, showing its versatility and potential for use with a range of equipment.

This DIY focus/zoom motor system offers an exciting opportunity for anyone interested in motion control technology. Its affordability and ease of assembly allow users to explore this feature without significant financial commitment. Whether you're a hobbyist testing the waters of focus control or a filmmaker seeking to add motion to your shots, this system provides an accessible starting point.

If you decide to build this FZ motor, the creator invites users to share their results, encouraging the community to post their creations and experiences. This openness fosters innovation and allows others to benefit from shared knowledge.

For anyone looking to delve deeper into affordable motion control technology, this geared stepper motor presents a promising solution.
