Compared to... Casio EX Z1000

There's an increasing number of cameras in the 10MP 'style' compact sector, and the Casio EX-Z1000 - as well as being one of the first - is one of the the best. So let's see how it fares next to the SD900 in our standard studio comparison. We've included samples at each camera's lowest ISO setting, and ISO 400 (for the SD900's higher ISO modes see later in the review).

There's not enough difference here to show in a standard sized print, but the SD900 is producing - by a small margin - the better result. In fact my first reaction when looking at the SD900's output was how good it is, not only by IXUS/ELPH standards, but compared to many 'high end' enthusiast cameras. Put these results next to Canon's range-topping PowerShot G7 and you have to look quite hard to see the difference. Color is excellent, and there's none of the over-sharpening, excessive contrast and over-saturation that blights many 'point and shoot' compacts, including, it has to be said, the Casio shown here. There is the merest hint of corner softness, but compared to most IXUS models it's very low. Very nice.
