Nikon E 50mm

I got a Nikon E 50mm. After reading all the good things about it by Kenrockwell, I decided to get one. I think this lens takes great pictures but focusing is a pain though. If focused correctly, this lens is capable of taking very good picture. The pictures came out really sharp and crisp. But I had to throw away eighty percent of my pictures because of soft focus. Again, bad focusing is entirely my fault, the lens is perfect. My version was okay, no visible dust and issue. This is a thirty years old, so I should not expect too much. Here are some sample pics.
