Just recently acquired a Panasonic 20mm pancake for my Olympus E-P1. I thought I'd have a look at which produced the best shot, side by side, between the new lens and the kit zoom. It's just a quick test, that I did a moment ago here on my desk at work.
The photos were taken a few seconds apart, from the same position on a mini tripod, framed to be as precisely the same as possible. The exposure was 1/15 at f/5.6 at ISO 200. These are the JPEGs; raw images are available if anybody's really that interested.
The first one is the Panasonic, the second one is the E-P1's kit zoom. Click the images for the full sized original. The resized ones aren't much cop.
Immediately you'll notice that the photos are not identically shaped. Although the focal plane to object distance was identical, the zoom lens' objective element was much closer to the subject, and the lens itself reported that it was at 18mm. When shot at 20mm , the framing was noticably different. I went for similar framing, rather than similar EXIF data.
As for quality? You'd be hard-pressed to see a difference. The Panasonic really shines when its aperture is open wider than the zoom lens' is able.
