For auction a RARE, very early serial # (only in production for two years) 8 element Asahi Pentax 50mm f1.4 prime - a great, classic normal lens sought after for it's sharpness and incredible bokeh. 

Being M42 mount, this lens can be adapted to pretty much any DSLR and all mirrorless cameras with a cheap adapter (Leica M, Fuji or Sony a6000,a6300,a7,a7ii,a7rii).  

The lens is in incredible shape for it's age.  Glass has no haze or fungus, focus ring is smooth across the range, aperture ring positive and clicky.  You won't find a better copy of this lens!  

Sale is final, so please ask any questions before bidding. Good luck!
