FS: Pentax Cosmicar 12.5mm f1.4 C-mount with M4/3 adapter
  • I have a couple Pentax Cosmicar 12.5mm f1.4 C-mount lenses. They have been modified to fit on a C-mount to M4/3 adapter (the barrel needs some filing to fit the adapter, done on a lathe). They have been shimmed for proper infinity focus and adjusted so the aperture/focus markings are upright.

    There is vignetting. I will upload some test shots soon.

    You get:

    • Pentax Cosmicar 12.5mm f1.4
    • C mount to M4/3 adapter (black anodized aluminum)
    • Front and rear caps

    Optional features:

    • M4/3 AF-confirm chip, mounted on adapter
    • Click-less aperture
    • C-mount to Nikon J1/V1 adapter (instead of M4/3)

    Asking price: $150

    I will ship worldwide, contact me for a shipping cost quote. Let me know if you have any questions.
