DG is a anti-reflective coating to minimise reflection from a digital sensor to the rear lens element. In my experience this may occur only 1% of the time and in a widelife setting less than that!
For DOF, please read the following link, an excellent piece one of a series writted by Yelvertoft. The other three in the series a well worth a read.

Thanks for the info. I will look at the cost of the Canon IS range. Would you agree that it would make more sense to stick with a fixed 400mm or 500mm lens rather than go for a zoom?? Something I hadn't thought of before Petes response.
Thanks again.
