Mamiya Tele-Extender?

[Mort54]

Hi All. Does Mamiya offer a 1.4x tele-extender for their lenses? I haven't been able to find one in any of their literature. An extender certainly helps fill in the gaps in a lens selection.

Regards,
Hans.

Mamiya offers only a "Teleconverter" 2X for the 645 Pro lenses. I have not been able to find any info as to if it will work on the AF models in manual mode (i.e. using 645 manual focus lenses with the teleconverter on the AF and AFD models).
 
The MAC Mamiya site FAQ section has this to say aboutr the teleconverter -

Q. Which lens will the 2x teleconverter work with?

A. It works best with the 150mm-500mm lenses and the 50mm shift lens. It cannot be used with the zoom lenses since the rear element of both lenses will be in the way.
