I’ve given it a quick test (6.2) with both my Canon Digital Rebel XT, and the Fuji S3 Pro.

Testing a Canon shot @ ISO 800 with my 70-300 lens, shows that the noise reduction is just like anyone else’s. I don’t see anything out of this world really.

With the Fuji, it was significantly noisier then what Lightroom can produce.

For optics correction, it’s still a awesome program. But for pushing my camera’s high-ISO abilities…I’ll pass.
