You can find all flange distances on Wikipedia under camera flange distance. It is the same as Mamiya 645 mount.

Thanks Mark, will try, but his Ebay advertisement specifically excludes the United States for some reason?

Cheers,

Peter

Dear Mark,

Thank you very much for this detailed response. Unfortunately, the seller does not ship to the U.S.A., but I will write him to see if I can change his mind or find someone in the States to do the mod.

Who/how was the conversion done, since the flange distance is very much shorter for the Samyang- either in Canon or Nikon mount- shift to Mamiya lens mount?

Many thanks,

Peter

I stand corrected. I must have been thinking about the 25mm. Unfortunately, 28mm is only about 24mm on the 645z, which is not wide enough for many of us...

Thanks for this extensive test. I think I read somewhere that the sample variations were ultimately what caused Pentax or it's successors to discontinue this lens, something I find to be a problem and has kept me from expanding my 645 shooting rig. Ultimately, with Fuji and Hasselblad now issuing lenses in the ultra-wide category that Pentax first served, it is hard to justify big bucks for acquiring new digital bodies and lenses when you are a wide-angle, landscape shooter like me - sadly.
