I just bought a lens adapter that should enable me to use Mamiya 645 stills lenses on a B4 mount. I shoot wildlife films and often need long telephotos, so this would be very useful. I have tried a 100mm,200mm,300mm & 500mm lens each with a progressively worse problem. None will allow me to reach a far infinity focus (a distance of approximatlry 1/2 mile or more). I am guessing the mount is just a fraction too deep. I am using a Panasonic HDX900 camera. Does anyone have any suggestions othetr than returning the adapter? Thanks

There is no back focus adjustment, otherwise I would have tried that.
