Sears 70-210mm f4 Macro

    I was hoping to get a good copy of this lens but I didn't.   Sure, it's clean and working perfectly, but it suffers from 'third party lens syndrome'.    These lenses were often inconsistent.

     I have  noticed fringing up thru f8 on light and dark edges.    

     Vignetiing is noticeable at f4.

     Corner sharpness is low and uneven.  It's possible that there i a misaligned element.   Dispersion is the major problem with this lens.   

     It performs best at f11.   Contrast is low at 210mm but sharpness is comparable to 70mm.  F4 is very soft, full of chroma, and fringing.

     Macro mode is not user friendly or useful.

     I have seen pics from other Sears 70-210's that compete with prime lenses but this lens doesn't even come close.
