    I noticed that I had three MFT lenses that covered 14mm, so I did a quick comparison shot with them just for kicks. The lenses are Panasonic 7-14/4, Panasonic 14/2.5 (pancake), and Olympus 14-42/3.5-5.6 II R (kit). All the shots were at f4, and the camera was an Olympus E-M5 on a tripod with the in-body IS off. The target (a photography book cover) was about 2 feet away, and the shots below are center crops.

    As you can see, the 7-14 is the sharpest and contrastiest, as it should be since it also costs about 3 times the other two combined. :p The pancake is actually pretty decent, especially considering how ridiculously small it is. The kit is noticeably softer than the other two, but it's being shot close to wide open here, which is not optimal for this lens.

    To elaborate a bit on the stopping down part, in my experience the 7-14 is sharpest wide open across the whole zoom range (f4), the pancake improves about a half stop down (f3.2), and the kit needs at least a stop or more to hit its sweet spot (f5.6-f8). So the test shots would have been a bit closer if I instead shot each lens at its optimal aperture. However, the ranking would have stayed the same.

    Thanks for that. It's great you've taken aperture into consideration, I think my 14-45 performs really nice at 14 when stopping down to f4.
