I have looked after about 3 months of Superior, check with friends and reading of test reports, Sony bought. Compared I have here, the Canon Ixus 40, Casio Exilim Z55 and the Panasonic Lumix DMC-FX7. The Canon is to say that their noise is out of the question badly, and when it becomes a little darker, makes red eye at almost every photo. I know what I'm talking, a friend of mine had the go away with. Moreover, it also indicates no battery life! For Casio Exilim Z55, although they make nice photos, but the photos are so grobpixelig that one knows whether they have become what never or not due to the 2.5-inch display. Exactly the same is with the Panasonic because the resolution of the large display is to bad at the photos to see if they have become what or not. What's more, that it has no optical viewfinder, which make photos in direct sunlight on the display makes it almost impossible. For new Canon series (Ixus 50, Ixus 700) is to say what one reads, but that they have only improved the resolution the old mistakes with noise, have no battery and red eyes not extinguished still! I am very pleased with the Sony, because it really does not have (at least sehbares) noise and makes no red-eye without red eyes flash. The camera is currently safe the best compact on the market, where even to the price / performance ratio. For this I would to Sandisk Memory Stick Pro Buy 512MB. To 1. exploit the high resolution, and to exploit the endless 2. Video function. In addition, the camera works faster with the PRO Series of Memory Sticks. In sum: very recommendable !!!
