A new era begins for Tamron as the company famous for its zooms moves into the premium fixed-focal-length lens market. Damien Demolder tests the first, a 45mm fast standard.
Tamron SP 45mm f/1.8 Di VC USD review – Resolution
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.
