JJC LH-60 Lens Hood for Canon EF 75-300mm 4-5.6 III (Accessories)
I recommend to all who have a telephoto lens with 58mm diameter, this diaphragm. She is very well, probably as good as the originals. But 4 stars because my lens does not Bajonettanschulss, only the Filterschraubanschluss. That was not specified.
