Danny, First I would check the mechanics: Was the lens assembled correctly afete r being mounted? Does the GG line up with the silm plane in your holder? Is either out of spec? Have you trired with a different holder. iuse QL all the tim e and have tested my QL holders against a variety of differnt holders and found therewas virtually almost no difference with my cameras (Canham DLC & Arca Swiss 4x5 F-line.) with the lens (a 210mm f/5.6 Nikkor W) wide open and no difference with with the lens stopped down to f/16 and f/22. The test were ma de on Velvia QL and Velvia 4x5. Your images should be sharp. Something in your imaging system: either your camera, your holder or the combination of th e two, is wrong.
