The reality is, you've bought a brand name which is industry famous........how can you go wrong really ?....they have their name for a good reason.......personally, I've never owned a Canon, but have been aware of them since back in the film days of the AE-1 which was a very good camera and very popular........as for your question on the Digic II ......its the processing engine which converts the light image captured into digital information for saving to the memory card.......and as the name implies, its the second generation of that processing software......good luck on learning how to get the most out of your purchase, and we wait here for some results.......most comments you'll get, should be taken as constructive and not critical....enjoy ! 

When I was in high school a friend of mine dubbed me "Chuckie" 'cause he said I resembled the actor......when I look back now at some old shool photos, I can see why.........
