Neuro....I have to ask the question; why?


You have the 2 best lenses in your bagto cover the 70-300 (400) FL....again, why spend 800 bucks for the redundancy of an inferior lens? I'm using "inferior" to compare IQ to the 70-200 ll and 100-400 IS.


Is the money worth spending for; low profile, weight, and inferior IQ?


White and weight are not factors for my lens decisions....IMOI'd opt for a lens that isn't in my bag, e.g. macro, prime (135 2.0) or some accessories you've been lusting over.
