The 1st difference, and arguably the most important one, is the image sensor's size. DSLR has an APS-C or Full-Frame (35mm) sizes CMOS sensors, where Powershots have much smaller, some CCD some CMOS sensors. this translates to superior image quality in terms of digital image noise - the larger the sensor, the less noise is apparent in the image.Cameras have come a long way and have evolved a lot. The Canon PowerShot SX30 IS Bridge Camera camera has CCD Sensor sensor. As far as the ISO levels are concerned, this camera supports Auto, 80-1600 ISO.
