Plainly, the 2 cameras posses different resolutions and different sensor measurements. The LZ20 featuring a smaller sensor will make shooting bokeh tougher and the Panasonic LZ20 will produce more detail as a result of its extra 4 Megapixels. Greater resolution will let you crop images somewhat more aggressively. The newer LZ20 will have an advantage with regard to sensor innovation.
