Yashica test

[Himself]

I did a comparison between Yashica ML 55/2.8 and its bro Yashica ML 55/4. The 55/4 it's not the model that you might be used with. It has an outer rim. I ransacked all possible forums, ebay, etc, I asked Koji, nobody knows anything about it.
Tripod,cable release,RAW,no PP at all. I threw in His Majesty Contax S-Planar 100/4 just for fun. I tried to frame it accordingly.
