This lens is very unique and there are several excellent reviews online (here, and here). I will echo what others have said: at f/1.8 - f/2, the spherical aberrations render a soft, dreamy glow. By f2.8, the glow occasionally appears in highlight areas. From f/4 onward it is incredibly sharp. Bokeh is uniformly beautiful at all openings -- slightly busy wide open but I like it for that reason. Stop down just slightly to about f/2 and the bokeh is completely smooth. 15 aperture blades make for perfectly round highlights at any aperture setting. Preset functionality and T2 mount make it easy to adapt and use with any camera system. Focus is incredibly smooth. The lens focuses down to less than 5 feet, which is rather good considering the age of this lens.
There's much speculation about the manufacturer of this lens but the consensus seems to be that it's a Tokina. It does not fall within the standard serial number tables for early Vivitar lenses. It appears in the Ponder & Best catalog here.
This lens is an impressive creative tool. Build quality and handling are fantastic and it is an absolute joy to use.
