i'm off back to uni soon, which means i'm gonna have zero money to play with 
so i'm thinking i should buy me some lenses now, and then when i'm skint at least i'll have something to play with
i've got a d50, with the 18-55 kit lens and a lot of my photography is UE - which is why i'm looking at a wider lens.
does anyone have a sigma 10-20, what do you think of it. I'm expecting it to distort a bit round the edges when wide, but how much - i'm not sure.
i'm also considering a nifty fifty (f/1.8 prime), seen some shots from one and like the look. what do people think to these lenses?
