Minolta AF 50mm f1.7
I think this lens is pretty nice prime lens from Minolta era, with an unbeatable price (around $70) I think its a great buy compare to the newer 50mm f1.8 from sony. The only downside of this lens is the focus distance, and it's about 75mm on APS-C DSLRs. These make it requires some space to take pictures.
But still, I highly recommend this lens.
Here are some of the picture I took using this lens and a550.
