The Zeiss Ikon name was purchased/licensed by Cosina I don't think Zeiss had any involvement in the camera.
That is quite interesting since I know for a fact that Zeiss is still handling the service and repairs. I'm not sure how long that will continue since the camera is now discontinued; this will eventually become a problem. I use and enjoy Leica cameras as well but my regular rangefinder user is a ZI. To me it is just an excellent and extremely usable camera. I do send it in occasionally to have the rangefinder cleaned and adjusted. Eventually I guess I should learn how to adjust it myself but I haven't had to do that yet.
Interestingly my Leica cameras seem to require regular service as well but I continue to use them and don't consider the need for occasional service to be a problem. Regular service is kind of a fact of life with most mechanical cameras I am aware of.
BTW, I feel that Cosina Voigtlander is a really good manufacturer as well so I can't say that Zeiss did a bad thing in choosing them to manufacture their camera. The Bessa cameras are pretty good in their own right and are quite reasonably priced. I may be mistaken but it doesn't seem to me that spending huge amounts of money on equipment is necessary in order to get good photographs, or good service.
It certainly doesn't always work out that way but if you take care of things they will usually take care of you. The only camera I have ever owned for a long time and used regularly, for literally thousands of rolls of film, that seemed to just keep working well without any service has been my Pentax K1000. But I don't believe that is normal for most mechanical cameras. I bought mine in the late 70s and it has been serviced once in all that time while still giving good service. However I don't consider that to be normal though.
