Clearly, both of those cameras come with different megapixel count and different sensor sizing. The Digilux 3 due to its smaller sensor is going to make shooting shallower depth of field more challenging and the Leica Digilux 3 will provide extra detail due to its extra 2 Megapixels. Higher resolution will let you crop shots a good deal more aggressively. The older Digilux 3 will be behind with regard to sensor technology.
