Photos: Canon PowerShot SX1 IS and SX10 IS bring SX-y back

Canon is quite chuffed with the zooming, with a USM and VCM coupling for near-silent but still speedy in-and-out action. That's an Ultrasonic Motor and not an Unstoppable Sex Machine, incidentally, along with a Voice Coil Motor. You also get optical image stabilisation to deal with knee-trembles.
