No problem, I was really interested for a comparison.
Well, I think the E-PL1 still retains the detail. The difference is that the darker colors on the E-P2 get washed out more significantly as one goes higher in ISO and hence seem to show more detail, while that of the E-PL1 remains more faithful in its color. Washout can be corrected in PP of course, but at the expense of making the detail less prominent. Anyway, looks like even ISO 3200 is very usable when really needed. I even turned off all Noise controls for this test, and software like Noise Ninja or Dfine should clean them all up to the proper degree.
I was also very interested in the resolution difference a supposedly lighter AAF on the E-PL1 made. I think it is more prominent in lower ISOs like ISO 200/400, but I need to redo my test just to be sure. It's not as significant as seen on the Sigma or Leica M8/9 which have totally no AAF, but every little step counts. I only hope they can remove it totally in their "pro" version, if it ever gets made. Read a rumor that a new Panasonic will have one with no AAF at all.
The E-PL1 IBIS is supposedly 1 stop less than on E-P1/E-P2, but I am finding it easier to get sharp pictures using a 50mm to 90mm at 1/4 speed (my limit) handheld in free space than with E-P1/EP-2. I can only attribute this to the better grip of the E-PL1, plus an additional hand strap I added. So I guess these compensated for the 1 stop difference, plus a bit more. Every little thing helps, and I do have a soft shutter button on both.
A nice touch are the faint outlines indicating the area used for spot and center-weighted metering.
The 1/2000 speed limit (even 1/4000 sometimes) is a bummer using 1/4 aperture in bright daylight, though, so 3 or more stop ND filters needed.
I almost forgot it has a flash, it's the last thing on my mind. I just tried it in Auto mode and it is very good within its limits. I'll let others expound on that
