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 – Shading
Shading is quite visible at the widest couple of settings on this lens, but that is to be expected. It is rather nice, in fact, so long as you aren’t being scientific. There’s a maximum of 1.2EV fall-off of brightness in the corners at f/1.8, which diminishes progressively on stopping down. Most of us will consider it gone by f/2.8, although f/4 will suit the more picky.
