This seems to be a nice substitute for the default 18-55mm Kit lens by Canon-Nikon. Some features of this interesting lens:

1. Biggest aperture: f1.8 throughout the zoom range
2. Designed for APS-C-Sized Sensors (Cropped sensor DSLRs)
3. Compatible with Sigma USB Dock

From Sigma website: "The Sigma USB dock works in conjunction with Sigma Optimization Pro software in order to connect a photographers lens to their personal computer to update firmware and other parameters such as focus, and for the Sports category: Autofocus speeds, focus limiters, and optical stabilization functionality. Updating the firmware can be done via the internet. Sigma Photo Pro is available for Mac and PC computers."

A quick update for all Nikon owners. There is a Firmware upgrade for "Distortion Control Lens Data".  for the following Nikon Cameras :

D4 / D90 / D600 / D800 / D800E /D3100 / D3200 / D5000 / D5100 / D5200 / D7000 / D7100
