Conclusions from DxOMark:
A versatile telephoto lens choice for shooting a variety of subjects including sports, events, and portraits, the Sigma 50-100mm f/1.8 A’s great light transmission makes it the best-performing zoom lens for the Canon APS-C that we’ve tested. Sharpness is very good, too, with excellent results at f/1.8, although it’s not a massive improvement over the Sigma 50-150mm f/2.8 at f/2.8 (and indeed, the older Sigma APS-C telephoto is marginally better at the narrower f/4 and f/5.6 apertures).
With very good lens metrics for distortion, vignetting, and chromatic aberration as well, however, the new Sigma 50-100mm f/1.8 A stacks up as a high-performing all-round telephoto zoom that’s worthy of the high price tag for Canon APS-C shooters.
