I have several Fujica 670 and 690 cameras and all the lenses, including the ultra rare 50/5.6 Fujinon.

It is the equivalent of about 21* on a 35mm camera when fitted on the 6x9.

It just so happens that one of these treasured rarities is for sale on that famous auction site right now!

May be a once in a lifetime opportunity for someone.

Good luck!
