Canon EF to Pentax K adapter

Canon EF to Pentax K-Mount Lens Adapter

Adapts a Canon EF or EF-S lens to a Pentax K-mount camera body. This is a macro-only adapter — it doesn't preserve the correct flange distance for infinity focus, so treat it as a close-focus/macro tool rather than a general-purpose adapter.

What you'll need

  • 3D printer
  • Canon EF or EF-S lens
  • Pentax K-mount camera body
Suggested material: PLA or similar rigid filament. Print with the EF (Canon) side facing down.
