Please note that this is a screw in type hood. it will fit any lens that has 77mm rim. Please make sure that your lens has 77mm rim, or it will not fit. Mamiya made couple versions of 105-210mm lenses, other two versions have 58mm rim.
Hood is in an average condition. Rubber looks OK. Hood shows light wear. I don't see anything damaged. Lens hood looks and works good. This lens hood is fully operational and functions as intended. I would rate it a 8, on a scale from 1 to 10.
Hood is double threaded. It is collapsible.
