The A900 is an excellent hi-sensitivity machine. Capitalizing on retaining more color and dynamic range throughout the entire ISO range than most of its competition, the A900 manages this excellent performance characteristic for much less cost than its best rivals. What doesn't get talked about much when it comes to higher sensitivity settings is color output and print quality when processing is debated. Sure "some" companies work more noise reduction in the chroma category into their processing as well as make a bit nicer grain pattern, but does that translate into better prints? Color wise, no, it doesn't.
Raw software, ISO debates, who needs it? Lets have some fun using our A900 for Jpeg output and see what we can do.
