Excerpt: I have a 70-300 telephoto lens that I use for wildlife photograph. I tried to get this hood awhile back and was sent the wrong hood but I didn't notice it since I was not using this len for awhile. Now I have 2, one that works and one that I have no need for.
Excerpt: This lens hood fits perfectly, and the felt lining on the inside is a nice touch. It is very easy to put on & take off This was not the case with a cheaper version I tried. Save yourself the trouble & buy the Canon version.
