I have been testing a new lens adapter that allows me to use a Mamiya 645 lens on a B4 mount. It works great with lenses up to 200mm but the image is soft with my 300mm & 500mm. Both seem to work fine on a Mamiya stills camera. I am wondering if anyone has an idea of what might be going on? It is not a focus issue so much as a general softness across the whole picture. Thanks
