I recently purchased this contax is I have taken it on a day trip and it has been working perfectly the only fault it seems to have is it's shutter does not always fire properly it seems to work most of the time though. I am curious what the history of this particular camera is as it has a Jupiter 8m not the proper sonnar (a problem I intend to rectify), it also has witness marks on the outer bayonet
