Yashica ML 35mm f2.8

     Yashica ML lenses are often referred to as cheap Zeiss.   Yes, they were less expensive but most were far from cheap.   They are well made and most were made by Yashica to Zeiss specs.   Some were made by Cosina as budget options, like the 200mm f4 C.   Those lenses were sub par, but this lens is above average is all respects.    It is also quite rare.  
     The ML 35mm f2.8 looks and feels like a Zeiss Distagon.    Focus is smooth with strong dampening.   Aperture clicks are positive but not aggressive.    On the Eos M3 it handles very well.    

     Lens characteristics are consistent through all apertures and focal ranges.   
     Contrast is excellent.   

     Color rendition is superb.   

     Fringing can only be seen at 100% crop in minimal amounts.   

     Vignetting can be seen at f2.8 with a slight barrel distortion.  

     F2.8 is very usable.   F4 improves contrast and f5.6 is tack sharp.    

     Black and white tonality is excellent.   

     Bokeh fringing tests show some color shifting which actually increase at f4 as contrast increases.  At f5.6 it begins to correct.
