The f/0 could be due to the extention tube(s). Maybe there was not a good connection between the tubes contacts and the cameras. It really did produce a shallow depth of field. Also did you use Auto Focusing? That may have had something to do with it also, I am no expert on things such as this but if you are using Auto for macro, you might want to go to the manual mode of operation and set your focus pattern to the center sensor in the viewfinder and use manual focusing.
