The only downside I can see from reading about the new lens is that it is only for APS-C camera bodies, a real bummer for those who use full frame cameras. But look at it this way: Sigma is totally capable of releasing something like this (like make a 24-70 f/1.8? Please?) for a full frame camera. Honestly, it’s only a matter of time.
