Sears 80-200 f4 (likely made by Ricoh)

     There was a time when you could get a quality lens from Sears   Sears lenses were made well.  The 80-200 is a constant aperture zoom.   It has a 1:5 macro capability and is a one-touch, push-pull zoom.  Optics are multi-coated. The lens build is all metal.  
     For many shooters, this lens is a sleeper.  Based on my testing, I would have to agree.  The negatives:  Soft at f4 with noticeable green fringing from 80mm to 200mm.   The positives:  It sharpens up at F5.6 and is tack sharp at f8 through the entire zoom range.   No noticeable vignetting or distortion.  The combination focus / zoom  ring is very well dampened.   Bokeh is smooth.   No special procedure is needed to enter macro mode, just zoom in to 200mm and you are at 1:5 macro.  Color rendition is cool.  Contrast is slightly soft compared to a Takumar.  While I would not rank this lens as anything but consumer grade, it is capable of producing sharp, pleasing images and feels good in the hands.
