The list author says: "I tried to list some good lenses to use with your new T2i. There are plenty of options to choose from, but the ones listed below are what I chose to purchase. So far I haven't regretted my purchases."
"This camera is fantastic. The sensor is supposedly derived from the one in the 7D. It shoots HD video in 24, 30 and 60 frames per second. Its light weight. The photos taken on the camera look amazing. Its a good starter dslr."
"This lens is very convenient if you want to pack light. Its primarily used as my "travel" lens. The range that this lens provides is phenomenal. The images it produces are very clear and I didn't notice any CA in any of the shots taken with it. It does have pretty bad lens creep, so make sure that you lock it when walking around."
"I use this lens when I want crystal clear shots. It is fantastic for portraits due to the extremely shallow depth-of-field. Its fantastic in low light (although I wouldn't mind if it had image stabilization, which is currently does not). Overall, I highly recommend this lens."
