Quantaray 70-300mm f4-5.6 LD Macro lens

     This is a Tamron made lens.  It is simlar to the modern version except that it doesn't have an internal focus motor.   I tested the Nikon AF version on the Canon T2i with an adapter.  When I worked for Ritz camera I sold many of these lenses.  I want to be clear, this lens has great IQ.  At f4 it is sharp, especially from 70-200mm.  At f5.6 it becomes very sharp.   It is sharper than the current Tamron 70-300mm IS lens.  At 180mm f5.6 it is exceptional.  In macro mode it is exceptional at 180mm and focused down to 1:2 ratio in any f-stop.  At 300mm it is a little soft.  The lens does show purple fringing at highlight edges at f4.  It is gone by f8 and barely notieable at f5.6.  Bokeh fringing is noticeble in high contrast transitions at f4.  Bokeh is smooth for a telephoto zoom.  IQ is high.  This lens has good micro contrast.  Images have depth and texture.
