Vivitar 135mm f2.8

     There are two  Komine versions of this lens.   This is the first version with a metal focusing collar and 8 blade diaphragm.   It was made in the early 70's.  My copy is in excellemt shape apart from a collection of dust on an interior element.  This is not a close focusing lens.   Minimum focus is 4.5 feet.    

     Build quality is typical of Komine.   It is solid.   Focus dampening is excellent.  Aperture ring has clickable half stops throughout the entire range.  This lens is multicoated.    Focus throw is a tad long but that allows for more precise focusing.  Whwen shooting porttraits you will appreciate the focus thtrow.   This lens is designed as a portrait lens. 

     Color rendition is excellent as with most Komine lenses.   Saturation is neutral and natural as it should be.   

     Contrast is also excelent thru the entire range.  Shadow detail is well balanced with overall contrast.    

     Sharpness is a bit soft at f2.8 but tightens up quickly a f4.   I chose to shoot mostly at f4 during my test.   After all, this isn't a landscape lens.   As you can see in the pics below, though, it does very well in nature.  

     There is some purple fringing in extreme lighting in the corners but it is minor and correctable.   There is a slight hint of bokeh fringing but it is barely notuiceable in100% cropped view.   

     Distortion and vignetiing are non existent.   

     This lens was designed for portraits and designed well.   If you have a body with image stabilization this would be a great candid portrait lens.    My only trouble while handling this lens was stabilizing it.    It happens with most telephotos and is not a criticism of the lens.   I don't have young hands or great balance anymore.    If you are like me, use a tripod.   All shots below were handheld and most were backlit.

     While I wouldn't say this lens is better than a SMC Takumar 135mm f3.5 or a Sonnar 135mm f2.8, I would say it is a bargain for less than $40.   It is tack sharp at F5.6.   Keep in mind that there are several versions of 135mm f2.8 made by Vivitar.
