This lens is actually a bargain ; it will deliver excellent results even at 600mm to the condition of a steep learning curve and an intensive practice.reviewed February 2nd, 2016 (purchased for $1,050)
Once it's done, the lens is easy to handheld shoot
It's advisable to get the Sigma USB dock and use some customization settings especially the one that completely reduces the distracting jitteriness and twitching of the OIS, same for AF set priority to precision, and other AF micro adjustment if needed
Most pleased with it : highly recommended 4.5/5 !!
