Nifty Fifty, everybody needs one.  Challenge your abilities!  Known for excellent background blur, I think they call it "bokeh"?  Full frame and works out as a great 75mm equivalent portrait lens on a DX or APC-C body.  Used in excellent condition, clean, clear glass, minimal signs of use.  Comes with front and rear caps.  Check shipping options for best price, around a pound with packing.  U.S. only please.
