I am a novice to the better DSLR camera world, which I'm interested in as a dedicated hobby. I realize quality lens are where one must start, but also realize that multiple F2.8 LS macro lens can quickly add up when one wants to do portrait, macro, landscape and wild life. Thus my question of your views on whether biting the bullet and getting one lens that might possibly do eveything you need for $2700 is a viable option you would definitely consider or too compromising in your view? How much better quality could one expect with multiple more specialized faster lens and would that be worth gradually moving into. After all this is just a hobby.
