Panasonic GH2 automatically corrects lens geometric distortion and chromatic aberration. If I understand it right, it always applies this correction just after reading from the sensor — so the image ...
I've been thinking about Micro Four Thirds, which in many cases encodes distortion and chromatic aberration correction into the raw files. But, the raw processor I currently use (Bibble) ignores this ...
Most lenses tend to be expensive because the lens needs to be very complicated in order to correct for various optical effects (aberration, etc). Is it possible to build a sensor and processor ...
