I am looking to upgrade my existing 2.1MP ixus 330. Features I am looking at for the new cam are (i) it should be higher than 3.2MP and (ii) it must have a good zoom capability. For (ii), I found the 3X optical zoom capability of the ixus very restrictive and even though I am not a professional photographer, I would still appreciate the possibility of taking high zoom pictures.
I currently am looking at the C720 or C730, both of which have at least 8X optical zoom. Do these 2 take good pics at high zoom? I understand that at high zoom levels, the images can be blurred with unsteady hands -- do any of these cams eliminate this problem?
Can someone recommend some other models to consider? My budget would be below 400 and I am looking at 2nd hand models to achieve that budget.
