Olympus E-450 Hi ISO examples

We've had an Olympus E-450 for a few days, and I thought I would publish some in camera JPEGs grabbed at dusk yesterday at ISO1600. Noise reduction and Filter settings left at the default, that's to say the latter set to Standard, and the former left to Auto. The last frame is a 100-percent crop (SAT set to Normal). For the time being, Raw files can't be developed by LR, Aperture or C1 Pro.
