I bought Heligon 50/2 that is solid mounted on some "device". The device has focusing screen and no moveable parts. What is the purpose of this combo?

When I look through it, it behaves like viewfinder, but the image is upside-down. The device has Kodak logo, and "Made in Germany" inscription, so it's not some home-made thing. I'm really curious about it. _________________ Join me on Facebook: www.facebook.com/LensesVaultHQ |

The Kodak part is a close/macro -focusing device, likely parts of the whole system. I don't know of the Kodak system, but google Contaprox, it was a system for Contax rf-cameras.
If it is not intentionally fixed, the lens should come off. |

Thanks to your clues I've finally found na answer - http://retinarescue.com/groundglassadapter.html. It helps you to set proper focusing distance. I still can't understand why one should use this . _________________ Join me on Facebook: www.facebook.com/LensesVaultHQ |

Put the lens on the adapter, focus it, then transfer it back to the camera (taking care not to disturb the focus). Many companies made similar - and almost all of them were better! _________________ Hero in the 'messin-with-cameras-for-the-hell-of-it department'. Official. |
