I am enjoying using the DaYi 617 back on a Calumet Cadet. I typically shoot with no movements, or maybe a bit of forward tilt....that's it.... my problem is the Cadet is a PITA to carry around....can anyone recommend another compact 4x5 to use the 617 back with ? Would a Crown Graphic work ? note: the DaYi needs an international back ( graflok ) to mount. I typically shoot with either 90mm or 125mm lenses.
