Panasonic usually corrects for barrel distortion with in-camera processing, but it seems to have skipped that for the FX90. As you can see in the top shot, there is some very noticeable barrel distortion. With the lens extended, there's a bit of pincushioning, but it's barely visible. The center sharpness is good from the Leica lens, but it gets softer out to the sides. The left side was particularly soft on my review camera.
