First Anwser: No, because there is no removable lens on the SX30 it is not classified as a D-SLR.a
Finay Balfour: Actually, a few Bridge cameras have removable lenses, but that doesn't make it as DSLR. DSLR stands for "Digital Single Lens Reflex", which means that it has a mirror which bounces the view from the lens to the viewfinder, and locks up when you want to take the picture, and that makes the clonking sound widely related to DSLR cameras.
So, to conclude, no, the powershot is not a DSLR, because it does not have a Single Lens Reflex mirror lock up system.
