The Yashica-44 was Yashica’s answer to the Baby Grey Rollei. It was one of the first Japanese copy cats (it is believed the Primo-Jr came out first) of the 4×4 Rolleiflex … and it was so much a copy that Rollei took them to court about the appearance of the camera … Yashica was forced to make some colour changes, and the first version did not last long before it was replaced by the 44A (the 44A’s got teeth). There are 7 (8) different colour versions … and they also made a version with a light meter (LM).
If you really want some great info on Yashica TLR’s, including the 44, you should check out Paul Sokk’s site … everything you wanted to know about Yashica TLR … so I won’t say much more than this.
… and 127 film is still available for purchase.
