The Sony 50mm f/1.4 is the smallest and lightest of the 50mm lenses on test, and it has a very neat, uncluttered design. It's also got the best set of depth of field markers, covering f/4, f/8, f/16 and f/22. It's much less sophisticated to use, though. The autofocus is pretty fast, but there's a lot more mechanical noise than you get from the others.
