Hey ya'll. I was looking into purchasing a new lense with my upcoming paycheck. I wanted one that would give me some nice telephoto capabilities. My friend owns the 70-300, but was telling me about how he dreams to have a 70-200. I understand that it's an L-series lense, but can someone show me proof of its superiority? I'm a beginner, and it seems like why would you sacrifice 100mm. Also, do any of you guys find it annoying when you have a prime lense like a 400mm and you have to move back and forth with your legs in order to get a nicely framed shot? Thanks again!
