so, i do ALOT of traveling. i have a camera backpack, which i mainly use to just store my camera equipment. i have 2 lenses, 18-55 and a 55-200. i honestly HATE the fact that when i want my wider angle without having to stand way back from my subject i have to switch my lenses. i hate the fact that i need to carry my backpack around because of this. would purchasing a super-zoom, such as an 18-200 solve my problems? i know they are a bit expensive, but i would sell both the lenses i have now to get a super-zoom. i have a nikon d40 (so i need the motor in the lens, which limits me a lot). if i DONT purchase something such as an 18-200, i was going to purchase nikons new 35mm prime f/1.8. would adding that as a 3rd lens be a better option than just replacing them both with one? suggestions to ease my aggrivations!
