Something of a legend in its own right - this lens has a reputation of relatively strong performance for its year/class in combined with beautiful rendering. In my experience this reputation is well deserved and the lens creates absolutely beautiful images. It's a contemporary to lenses like the Takumar 50mm f/1.4 and my beloved Yashinon-DX 50mm f/1.4. My copy is in great condition and I was able to get it on auction for a good price.
