Canon EF 50mm f/1.8 II

Truly an amazing little lens..even if you drop it and the lens falls apart. It happened to me and I put her back together and it still works just fine. She can be a bit sensitive sometimes, even before the drop, and won't focus on what is being indicated by the AF point. Stop this little bugger down a stop or two and you will be rewarded with crisp images almost worthy of L glass.
