Title: Affordable Focus Control for Your Camera Lenses: DIY Motor Accessory and More

Ever wonder how those flawless focus transitions in films are achieved? Chances are, it's not down to a cameraman's nimble fingers on the lens controls. Instead, it's likely the result of pre-planned motor movements. To experiment with this cinematic magic on your own, [l0u0k0e] offers a practical solution - a 3D-printable focus zoom motor accessory!

The heart of this device is a geared stepper motor, and it comes with printed parts to complete the build. If you're working with a budget, PETG or nylon are preferred materials for the gears, though PLA will suffice, albeit with a shorter lifespan. Compatibility-wise, it's designed to fit standard camera rigs, including those with a 15 mm tube.

Connecting it to existing focus drivers is a breeze, and there's even an option to program custom Arduino sketches for advanced control, if that's your thing. You can find the model on Printables, making it easy to print and give it a go!

This focus puller isn't the first of its kind - in fact, you can even craft one with LEGO!

Dive Deeper:

  • Printables: The go-to platform for the DIY focus motor accessory, readily available for download and printing.
  • Hackaday: A treasure trove of DIY projects, including a LEGO focus puller as an creative, budget-friendly alternative.

The versatility of these DIY solutions means filmmakers can effortlessly fine-tune their focus control without shelling out on pricey professional equipment.

The LEGO Focus Puller:

  1. Construction: Constructed from LEGO pieces, creating a mechanical linkage that couples with your camera lens.
  2. Power: Typically harnesses a LEGO motor for automated focus pulling.
  3. Benefits: Highly adaptable and easy to put together using common LEGO components.

Additional Resources:

  • CineD: An essential resource hub for creating homemade follow focus gears using a 3D printer - perfect for customizing your DIY focus puller setup.
  • Yeggi: Offers a multitude of 3D models, including various focus-related accessories that can be tailored for camera use.

With these DIY focus puller solutions at your fingertips, precision and style are just a printer and some colorful building blocks away!

This focus zoom motor accessory, available for 3D printing, offers an affordable solution for filmmakers to achieve fluid focus transitions, using a geared stepper motor and compatible with standard camera rigs. Additionally, for those interested in advanced control, this device can be connected to an Arduino board for custom programming.
