With the Z2 price tumbling is the Z3 that much better? What, with the same panels, similar noise etc, only major differences seams to be improved contrast ratio, 10bit colour processor, better scaler and dust removal options. OK, so that's quite a bit, but will the picture be much better? I will be going from an AE100, so the Z2 would be a huge step, but it is 50% more expensive than the Z3? Azzo.
