I have found a great match for the E-P1 and all it's quirkiness. I paired up a newer Jupiter 8 with my E-P1 and it's a nice combo. The lens has a lovely quality about it and is quirky (the stepless aperture, rather long focus and placement of the aperture ring/focus ring). I find that the E-P1 needs a bit slower approach than other m43 cameras...and so does the Jupiter 8. I first put the Jupiter 8 on my G2 when it arrived and it was fine but nothing extraordinary. Then I put it on the E-P1 and it was love at first sight. They go together like cereal and milk.
