I made a couple of photos to see differences between these lenses plus I added one taken by Galaxy Ace (5Mpx).
Here's a link for a package in *.rar: http://speedy.sh/cSmVJ/N9-Camera-samples-comparison.rar

Both N9s had the same settings while taking photos. On is in taken using default app and the other using PCam. S5830 had all default settings.
One more thing. Photo list:
1. Small lenses, default app.
2. Small lenses, PCam.
3. Galaxy Ace.
4. Big lenses, default app.
5. Big lenses, PCam.

Comment on these? No, I think I won't do this. I wish I didn't make this comparison. Now I realize how bad big lenses are in N9.

PS: You can't see much as photos were resized. Even 5Mpx photo by Samsung doesn't seem any worse.
Photos are untouched in the package.
