The 20mm results looked very similar to what I've been getting on my G-series cameras. The 7-14mm results looked slightly worse on the EP-1, but this is marginal. The surprise was that the pictures taken with the 45mm macro looked better. Very sharp indeed.
This is only a first impression and using the lenses over a period of time will reveal more.
Its a nice camera to use. I'm not missing the EVF as much as I thought & it feels very good in the hand.
