I have acquired the top of the range lens (currently) for the Canon’s cropped body despite every cell with a sense of financial intelligence in my body protesting against it. It’s a bloody expensive lens, and I’m still paying it with my blood and sweat. It’s a really painful purchase which still resonance till now.
