As a landscape photographer who is addicted to the big vista, I have often wondered just how hard or easy it would be to force myself to only use one lens, and that lens being the 70-200mm. The versatility of this lens is fantastic, and many of you will know this already. However, the best thing about having my 70-200mm is that it's always in my bag and ready to be deployed whenever I need it, but what if I were only to have this lens?
