Had my IR modified Oly EPM1 back from repair for a couple of weeks now.
While the EPM1 is nice & tiny, it is very hard to hold onto. The smooth metal finish is ...er.. a bit too smooth
I picked up a Flipbac grip for the front, and the same thumb grip I have on my EPL1. Approx $25 all up from ebay
Now I can finally hold the camera in one hand without fear of dropping it
