Question What's the difference between DC/DG in SIgma Lenses

Because of budget, I am looking at either 20-40mm F2.8 EX DG ASPHERICAL or the NEW 18-50mm F2.8 EX DC. Anyone know why, I should not go with the 18-50. I've been to the site and can't really decifer the difference between DC & DG. ANy help would be appreciated.

DC lenses will only work on crop cameras. DG lenses have a coating on the glass designed for use with all digital cameras. So in theory a lens can be a DC and DG.

Go with the 18-50.

go with the 18-50mm...

EX (EX Lens)
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.

DG (DG Lens)
These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.

DC (DC Lens)
These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus ! including compact and lightweight construction.

DC lenses are sigmas answer to EF-S, but DC lenses can be mounted to a 1.3 crop or full frame camera, they will vingette though cutting off the corners.
