You have the "Hills and Valleys" version of the 58f/1.4. It is a very interesting lens although quite unpredictable. I have taken some great shot a with it and other times flare seems to mess up everything.

If you ever come across the MD 50f/1.4 grab it. It is a much more consistent lens, sharp from f/1.4 and handles flare better.

The third-generation MC Rokkor 50mm 1.4 (rubberized focusing ring), is also a highly regarded lens.
