After breaking the hood of my 80mm and 65mm Mamiya 7 lenses, I decided to design and manufacture a new inexpensive version to replace the original. Having considered other options on the market, such as the screw-on sort, I decided not to chance possible vignetting from stacking a screw-on hood with a filter. so I decided to make a bayonet fitting version.
