For sale is my Fujinon 50/1.4. This is a fantastic lens. Amazing bokeh. Basically identical to the SMC Takumar, but it has the special Fuji EBC Coating which gives superior color contrast.
Optically the lens is in great shape. There is a slight bend in the filter thread, but it still accepts filters.
