And it takes photos like this? http://i.imgur.com/BK5vPRw.jpg I'm desperately trying to find which lens will allow me to take photos like this. I already have a canon camera.
The lens in the camera in the picture you linked appears to be either the EF 50mm f/1.8 or the EF 50mm f/1.8 II. The latter can still be purchased but there is a newer version, the EF 50mm f/1.8 STM, that was recently released that is available for about the same price new.
Here is an excellent review of the newest version that compares the two.
Please don't take pictures like your example, though! Not only is it trespassing to be on railroad property but it is very dangerous. Trespassing on a bridge or trestle is particularly hazardous because there is no quick escape route if a train approaches. There are between three and four hundred deaths per year in the united States due to people being where they shouldn't on railroad property and being struck by trains. Trains can't stop very easily and usually by the time they see a person on the tracks it is too late for them to stop until they are well past the point where the person was spotted.
Looks like the canon 50mm f/1.8, to me...
