I want a new lens for my 400D, until now i've used the 50mm 1.8 for everything, but i want something that doesn't zoom that much without me doing it manually (if you get what i mean). I mostly take nature and city pictures, but also the occasional parades, events, portraits and formal party pictures. So what i want is maybe a wide angle lens or a zoom lens. plus, i don't want to pay much more than $250 since i have to pay 25% tax when i import it here. Any suggestions?
