Sony Cyber-shot HX30V Digital Camera Review$369.99
We found little chromatic aberration in most of our test shots, as it seemed to mostly be controlled by the camera. There is ample evidence that it is there, though, with heavy diffraction and a strong purplish hue in the corners of many of our test shots. In this case the purplish border shows up mostly in areas of contrast in the middle and telephoto ends of the zoom range. It's not overly distracting, but it could seriously impair certain high-contrast shots from time to time.
There's always going to be sacrifices when you're designing a compact 20x optical zoom range lens. The most usual error is going to be distortion, though we found little evidence of that with the HX30V. The camera produced less than 0.25% barrel distortion at the wide angle end, with that becoming a practically nonexistant pincushion distortion as you zoom in through the rest of the focal range. This is likely the result of software adjustments, but there's even very little distortion when framing shots on the rear LCD. The HX30V may be employing tricks to cover up for lens errors there, but with no visible signs of image quality degradation, we're okay with it here.
