JPEGs look clean through ISO 400, but you can see some slight mangling of details starting at ISO 800.
By ISO 3200, sharp and properly illuminated areas show a little degradation, but shadows look mushy. By ISO 6400, you really don't want to use JPEGs at full size.
Sharp areas look a tiny bit soft -- which actually works in its favor -- in the expanded ISO 100 range.
Sharp areas can look a little crunchy at ISO 200, the camera's lowest native ISO sensitivity.
Sharp areas at ISO 400 look very good.
In-focus areas look fine in ISO 800 JPEGs, but you can see noise-suppression artifacts in the out-of-focus areas.
The artifacts in out-of-focus areas are even more pronounced at ISO 1600.
You can get much better results in high ISO sensitivity images by processing raw files.
I probably wouldn't use ISO 3200 JPEGs at full size.
Olympus defaults its cameras to the Natural color setting, which delivers pretty accurate results.
I find the standard white balance produces very cool results indoors, and prefer the setting to preserve warm tones.
The 50mm f1.8 delivers very nice out-of-focus highlights for the money.
The kit lens delivers pretty typical results.
