I would like to know if replacing my 70-200 2.8 IS with a 85mm f/1.8 USM and a 200mm f/2.8L II USM. I feel I never use the 130mm of this lens. This lens is a pain to carry around and I don't seem to feel the love I did with my 70-200 f/4 IS. By doing so I would even be able to buy a 3rd lens with the extra money.
