to pick a lens? My thinking is that I'm going to need at least 3 lenses to make me happy...I have my 50mm which is great, but so limited. When I walk around I get so frustrated that I can't capture the bird in that tree and I can't take a decent macro. I also really want a decent wide angle, and in the house I often can't get far enough away to take a good pic with my 50mm. So, what do I get first? I really want a quality lens that is going to last me...I don't want to have to re-evaluate in a year and have to buy a new lens with the same reach as my next lens purchase. What do you think will serve me best? What lens do you use the most (besides your 50mm)? I'm not asking about the specific lens, just the range.
