I have a Gaoersi 4x5. There might be several different models, but this is a metal frame camera with separate lens cones and graflok back, with removable groundglass. Not sure what kind of experience are you looking for. It is a simple, solidly built camera. I have never seen a Dayi 4x5, but I think they make 6x17 backs for view cameras.
