The Sigma came UPS yesterday. Due to prior commitments I was unable to unpack until midnight last night. It is a much more substantial lens the Nikon kit lens. It is bigger and heavier than the Nikon 50mm F1.8. It focuses fast and with the HSM almost silently. I need to get out and snap a few pics to see how it performs but life looks like it is in the way for the next few days.
