I'm looking for a mildly inexpensive lens for my Nikon D3100 camera, that I can use to take wide field of view photos. My parents got me the AF-S DX Nikkor 35mm f/1.8G lens for Christmas, but the field of view on it is no different at 35mm, than that of my 18-55mm that came with my camera. Am i going about this wrong? Do i need a fisheye for what i'm trying to do? Please help.
