This i a very interesting Kiev 4 (?) camera wiki entry that warrants some discussion, first of all it has the "T"-shaped ridge on top of the light meter which is fairly atypical for the 1957 Kiev 4 and what happened to the flash sync contact? this is extremely weird. Denn I saw you post this, is there a photo of the bottom of the camera? does it have a leg like III or it's flat like IV?
Here it is. The camera was restored by me, as usual with such old copies long shutter speeds did not work or the braid breaks. It is my rule that everything that comes into my collection must work. I can say that inside it is a classic Kiev II/III of later releases, except for the exposure meter of course. It is known that the prototype Kiev 4 was introduced back in 1951. In almost 10 years of collecting and restoring film cameras, I have come across cases of these early Kiev IVs. Some of them had synchro contact. There is an opinion that in the beginning of production the cases from II/III models were used. It is not known what this is related to. Perhaps they did not have time to establish production of new cases, or their quantity was insufficient. I think we will never know.
