hi... was wondering what wide angle lens are used for. been reading abt it but don't really totally understand.
a) from what i read, wide angle lens allows greater depth of field coz u capture more of the surroundings even those that are nearer to the camera. can't i do that by physically taking a few steps behind?
b) what are the most common uses and how to use? landscapes, architecture and street photos only?
c) are the lens really that useful?
*hehe* thanks for ur replies in advance =p
