When Canon announced the 100-300mm f2.8 L, we were pretty excited by the idea. I immediately thought that sports photographers would be most reaching for it. Indeed, it’s quite a revolutionary lens in the mirrorless landscape. But at the same time, most photographers who use it use it for wildlife. And with that in mind, I started to scratch my head. Canon already has its exceptional 100-500mm L lens. For years, I’ve used this lens and known that it’s incredibly effective for that type of work. So, after some time away from both the 100-300mm and the 100-500mm, I’ve channeled a lot of thoughts into which one photographer should use.
