She's seventeen years old already, but I love her as much as the day I decided that I could actually handle a 13 pound+ lens and first got her. Over the years this has been one of my most used lenses, I've traveled the USA with her. And her tripod.

However, now (many moons later) I do wish she was lighter in weight. Unfortunately, I can't afford to upgrade to the newer, much lighter 600mm DSLR Canon lens, not while Canon is gradually moving from DSLR's to mirrorless bodies & the future of DSLR bodies is uncertain.
