Olympus has just released a new compact camera, XZ1, which has a 1/1.63" CCD (similarly sized with Digilux 2) and a zoom lens which is 28-112mm equivalent, with F1.8-2.5 maximum aperture (maintains f/2.2 until 100mm).
Olympus XZ-1 Quick Preview Preview: 1. Introduction: Digital Photography Review
Looking at the photos of the thing, I was stunned how minuscule the whole lens unit is when compared what Digilux 2 has.
Isn't it interesting? How do they do it?
