Fifty years ago I purchased a Contax IIA while stationed in Korea. I still have the camera and it needs to be repaired the. The view finder does not focus. It has separated range finder for the other lenses I have for it. All Nikkor lenses. The Kodachromes I took with are extraordinarily sharp and even though I am totally digital today I would still like to use it with some film. Does anyone know of a repair facility?
Try to contact George, at Crystal Camera Repairs in Asheville, North Carolina and tell him about your camera. He can give you a good indication of what can be done.
I do not know if your lenses will work with the present Contax cameras but that could be a good way to get back into film photography, assuming your Contax cannot be repaired. They are smaller and have modern technology.
