You can get some very nice photos with the E-M10, though you might want to avoid using JPEG at the higher ISO sensitivities.
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.
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
