I have found duct tape and a Swiss army knife or a leather man knife is all that one needs to carrier into the field, more then a half mile from the car. The car has a tool kit in it that has everything I may need. And for those lenses that like to go swinging most corner stores have a cure. I have found that repair that happen in the field fall into two areas. Minor break or problem that can be repair in the field or major breakage and cannot be repaired in the field. I like to travel on the light side and my feeling is if I canít repair it with a Swiss army knife or tape its time to pack it in.
