Expensive fun

Canon Lens Hood is typically not buying a lens case. Since I no longer think much of affordable UV Filter by bad experience, I decided principally for reasons of lens protection for this Streilichtblende. Because as a diaphragm itself is this little piece of plastic 2cm hard to use. I knew, however, prior to purchase, what I'm getting, there are 4 star because the part met its expected end, though (unfortunately) no longer.
