I've wanted a new lens for my Nikon D40 for a while, but I couldn't decide on which kind to purchase. After narrowing it down to either a 50mm or 35mm lens (nothing extravagant or complex), I decided to go with the 35mm because it is closer to what the human eye sees. I didn't want to worry about being too zoomed in all the time. This way, I won't have to back up as much. I can always crop in Photoshop later on anyway :)
I think it'll be a great walk-around lens. It also has decent bokeh, which makes me very happy!
