Tamron SP 85mm f/1.8 Di VC USD £750/$750
A SOLID PERFORMER IN EVERY RESPECT
Despite its much longer focal length, the big brother to the Tamron 45mm is actually a fraction shorter, and has the same 67 mm filter thread. It also shares the same combination of an f/1.8 aperture rating and VC image stabilisation. The styling, build quality and weather seals are also the same.
One notable difference, however, is that the 85mm lens is heavier, at 660g rather than 520g. The main reason for this is that it features 13 elements, compared with just 10 in the 45mm. Both XLD (eXtra Low Dispersion) and LD elements are included to reduce aberrations, and two types of nano structure coatings are included to combat ghosting and flare.
Bokeh is even smoother than in the Tamron 45mm lens, but coma is a little more noticeable at apertures wider than f/2.8. Autofocus is faster, but the manual focus ring has less rotational travel. Again, centre sharpness is impressive when shooting wide open, but here it’s also excellent right out to the extreme corners of the frame.
