Verdict
The Sigma is an impressive lens with only few weaknesses. The resolution is
excellent at 50mm and 100mm and (roughly) very good at 150mm although the
quality could be a little better at f/2.8 here. While not formally tested
the close focus performance (@ 150mm < 1.5m) seems to fairly poor.
Distortions and CAs are well controlled. Vignetting is a slight problem at
150mm @ f/2.8 only. The bokeh (out-of-focus blur) is pretty good especially
for a zoom lens. The build quality of the lens is excellent although some may
miss a tripod mount. The AF is a bit unsure at times but the AF accuracy of
the (serviced) sample was generally fine.
The question of the day is probably - Sigma or Tokina ? That's too close
to tell I think.
