Thank you, I am not sure what a Miranda mount looks like on the inside, this has a ring like the inner on a T2 but it is almost 44mm, it is not threaded. I would have thought an outer ring would go over it to adapt to different cameras?

Not the best pics but I hope you can see the difference from a T2 ring, also the lens focuses beyond the infinity mark. http://forum.mflenses.com/userpix/20247/12653_DSC00328_1.jpg

An M44 screw mount would be for miranda cameras. 41.5mm registration distance so a longer than average mount.


?

Yes but it is not threaded, it has the ring that is similar to the ring in a T2 adapter but is smaller than T2. I have M44 adapters but is not even close.

Most T2 outer ring inner diameters range from 46 to 48mm this ring is permanent.

Got it. Check greyscale post on first page of this topic, especially the last line:

I was researching an unusual lens that I came across on ebay when I stumbled upon this thread. The lens in question is a "Super Yashinon-R 1:3.5 18cm", in the proprietary Yashica "Y" mount for Yashica's early "Pentamatic" series (pre M42). What led me to this forum was the red K.C on the front of the lens, which I have never seen on a Yashinon lens before. Studying the pictures in this thread, it seems obvious that the lens pictured in the auction below:

is a Kyoei Acall 180/3.5 in Yashica "Y' mount. What is even more interesting are the adapters for M42, C/Y, and Nikon included in the sale.
