I really liked the OMD-EM5 and EM1. And the MFT lenses really are wonderfully compact and have solid optics. I just kept running into depth-of-field and low-light issues, so I wound up having to buy the larger, faster lenses anyway - and was still fighting noise performance in high-ISO shots.
That’a lovely little unit! I wound up going with a Fuji X100 for that role - quirky, but fun.
