I have a nice Canon Rebel GS with Sigma lenses and a small digital Canon camera. I really like the quality of my larger camera over my smaller digital. The digital just isn't fast enough and I do not care for the overall quality of the pictures it takes and I feel like I miss great photo ops because it is being stubborn. I love my larger camera to take pictures, but in this day and age it is more economical to go digital rather than developing photos. I would like to upgrade to a more professional digital camera that has great zoom opportunities. What camera would you recommend I upgrade too, and where would you make this purchase?
