Permit me for asking this unstructured question. But how many people have found the Mamiya 7 lens shade to be a problem? I bought some equipment described as lightly used, and the lens bayonet, where the shade is mounted, has a gash. The gash was also covered up with a black marker, but not disclosed at all. My guess is the shade was forced onto the lens, and it chewed up a little bit of the bayonet. I am not sure why but the seller says that some people fuss over cosmetics. But he also blamed the 80mm shade as of poor quality, and hence the gash on the 80mm lens. How many people have gashed their Mamiya 7 lenses? Would you call it a lightly used equipment. The Glass is very clean. So, is the Mamiya 7 lens shade bad?
