Auto Tamron 135mm f2.8 (Adaptamatic)

     Here we have another adapt-a matic lens from Tamron.   It is well made.   Focus is smooth and it has a long throw.   I found it a bit difficult to focus on the EOS 6D, but the lighting was atrocious today.  

     Wide open it is usable but a little soft.   Corner sharpness is quite good, though.  At f4 it tightens up a bit.   Contrast improves along with sharpness across the frame.  

     Bokeh is smooth and this is to be expected from a portrait lens.   

     There is some fringing at f2.8 but it is minor an easily corrected.  At f4 it is basically gone.  

     This is a classic lens and its images have a classic feel.   I have no doubt it is a good portrait lens.   I can't wait to try it on a better day.
