Its not the tool but the one welding the tool.
I sort of dislike when people say this. Sure, it's true up to a point, but the tools have limitations. Case in point, trying to make the best out of a 60D and kit lens, but indoor shooting just doesn't work. You suggest I use the tools I have? Or wouldn't a camera that can do better at higher ISO/a flash/a faster f/2.8 lens not be called for?
Doing video, I am sorry but you just do not get the same look out of the kit 18-135 lens that you will from a 70-200, 24-70, etc. And it's not just about the look, but performance. I need low light capabilities!
