M42 Lens Adapter Kit

Unlock the full potential of classic M42 glass on your custom waist-level viewfinder camera.
This adapter kit is built for creators who want vintage character, sharper manual focus control, and a wider effective field of view—while keeping the modular spirit of the camera.

What’s Included

• M42-to-M42 Focus Helicoid
  Smooth, precise focusing with an extended throw for critical manual focus.

• 0.5× C-Mount Focal Reducer
  Concentrates the image circle for improved sharpness and low-light performance, reducing the effective crop factor to 1.6× when using full-frame M42 lenses.

• IR-Cut Filter
  Ensures accurate tonal reproduction and protects the sensor from excess infrared light, especially when using older lenses that transmit heavy IR.

Why This Matters

With the helicoid, focal reducer, and IR-cut filter working together, you get:

• A wider, more natural field of view

• A more “full-frame-like” rendering
