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,  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 reduced.  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.
