Kiron 70-150mm F4

     The Kiron 70-150 is sharp, contrasty and unusually well dampened for a one touch zoom    It is sharp at f4 with a pleasant bokeh.   

     There is minor zoom creep on my lens.   It can be an issue when shooting macro at a steep angle.

     It has excellent , full time 1:4 macro performance.

     It does suffer from noticeable fringing in high contrast scenes but if you avoid a stark white sky you will be very happy with the results.   

     It is relatively small so it will handle well on a mirrorless body.    It handles very well slr bodies.      Focusing is easy and it balances very well.  I have never had an issue with camera shake while using the Kiron 70-150. 

     This is one of my faviorite lenses.    It's build and image quality are very high for a lens that regularly sells for less than $50.
