It's not hard to figure out, but it surprised me a bit. Was just playing around, stuck in the house due to the snow. This is the RX100 vs. the EPL5 w/P20 f1.7. Focus point was on that blue and red pillow. RX100 shot was in camera jpg. EPL5 shot was RAW with LR "clarity" added. I stumbled upon this because I was testing the lens cap lens vs. the RX100, and thought they'd be a little close. Not even. So, I grabbed the 20/1.7 to test, and was very surprised how close they are. I'd even give the edge in sharpness to the RX100 (DR to the EPL5), but as it's not entirely an apples-to-apples comparison, I can't really draw precise conclusions. But they are in the same ballpark, surprisingly.
