Chromatic Aberration
We found that chromatic aberration was fair to normal on the NEX-F3. Lateral color fringing (the most obvious sign of chromatic aberration) was only really visible at the widest focal length of 18mm. There's significant color fringing present at all apertures tested at 18mm, though the other focal lengths presented few problems if any. The color fringing was mostly present in the form of blue/orange fringing around our slanted edge targets, giving them an ugly multicolor halo.
Distortion
Distortion becomes a bit of an issue of NEX-F3's 18-55mm lens as you go through the focal range. The wide end is predictably bad, with a barrel distortion north of 3%. This can be corrected in the camera, though there are occasionally some hitches and you get a slightly distorted final picture. Normally we see this correct itself to a nearly imperceptible pincushion distortion through the rest of the focal range, but the NEX-F3's overcorrection was drastic, resulting in a 2.32% pincushion distortion at the midpoint focal range. Even that wasn't brought back down to Earth entirely, as the full 55mm focal length still had a 1.32% pincushion bend to it with the in-camera lens correction deactivated.
