Never bow to peer pressureOriginally Posted by Adam Goi
if you are comfortable with zooms, use a zoom... if you wonder how a 50mm is like, just loan one for a weekend. You don need to buy a lens in order to test it.
as for why some choose a particular lens.. its just preference and intention since most choose the lens to give them the perspective they wish to achieve. In other words they have the photo in mind EVEN before they press the shutter.
