Launched in February 2011, the Sigma 50-150mm f/2.8 EX DC APO OS HSM is a trans-standard zoom lens aimed at APS-C camera users. On these APS-C models, the crop factor of the sensor (1.5x on Nikon and 1.6x on Canon) makes it comparable to the 70-200mm focal length on a full frame camera, but arguably with an even more versatile length as they reach a little longer (225mm on Nikon and 240mm on Canon). Featuring a raft of specification acronyms, it promises high performance in a well-priced package, but does the reality live up to the billing?
