Tamron SP 45mm f/1.8 Di VC USD review – Resolution


Centre: solid, Corner: dotted

Resolution is pretty good at all aperture settings and, while of course corners and the centre get better as we close down, I was pleased with the amount of detail gathered at f/1.8. The best overall aperture is f/4, with the corners catching up by f/8, but sharpness tails off from f/11. It is interesting to see that wide-open resolution is better than when the lens is fully closed.
