Tamron AF 28-200mm F/3.8-5.6 XR Di Aspherical (IF) Macro

Lens | Canon EF, Nikon F (FX), Pentax KAF, Sony/Minolta Alpha

when stopping down to f 8-11 excellent sharpness between 50 and 135 mm, but good sharpness at extreme tele and wide angle with some CA's in tele range. nevertheless  an eighty per cent lens because of its very good correction of distorsion, very nice colors, high contrast and over all good sharpness, when stopped down a few.
