Olympus SZ-31MR iHS Digital Camera Review$399.99
Chromatic aberration seems inversely related to sharpness in the SZ-31's case. At the closest focal length, where resolution is best, fringing is very noticeable in high contrast areas that have already been affected by edge enhancement (notice the hard black lines in the 4.5mm crops below). Once sharpness starts to deteriorate at the middle and far end of the zoom range, chromatic aberration still exists but starts to blend into the general blur of the scene. We're not sure which is worse, frankly.
In keeping with what seems to be this camera's trend, distortion is barely detectable at the closest focal length, but as the optics struggle to create that incredible 24x zoom, distortion is introduced. Pincushion distortion reaches 1.35% at the middle focal length, and flattens out to 0.99% at the maximum. Casual photographers probably won't notice, but if you're really concerned about distortion, just zoom out.
