Sigma lenses (and maybe to all third-party brand lenses out there) is comparable with Nikon D lenses and Canon non-USM and Canon L lenses. When it comes to its bokeh, toning, colors, saturation, AF accuracy, AF speed and sharpness.
PS: the drawbacks or the bad thing/s
1. bad AF accuracy, the AF is not that accurate.
2. AF speed is pretty slow dude, it has a 1 second delay most of the times.
sigh.
:/
