Hi BC..

 

..You know me BC, in between looking up the flange distance and writing it down I always make some sort of  error.....yes 28.8mm,........then it's just a question of finding an adapter for the Pentax K mount for my very appropriate K01 with focus peaking........I will check it out....

Uhmm, that won't work? The K01 is about the only "mirrorless" camera with "mirrorbox", giving it a flange distance of 45.46mm.

I think it will be hard to find an adapter with a thickness of -16.66mm? It would fit just fine on my cheap EOS M with the M39 adapter I got from... China.

 

​Probably I am misunderstanding your post?
