Is it the lens, or the camera, which contains the correction parameters for the lens in question? If it is the camera, the camera's firmware needs to be updated and expanded with every new lens release.

If it is the lens, which plays part in this, for the Panasonic cameras the situation gets a bit more complex, as there are 2 sensor sizes... the GH series has bigger sensors that allow 16:9, 4:3 and 3:2 formats, which all would need a different amount of correctiing.[/quote]

To me it would be most logical to put the correction data in the lens, exactly as you say if it was in the body you would constantly need to update the firmware every time a new lens came out. Well, each time you buy a newer lens at the least.



I don't see an issue with the varying aspect ratio sensors as the image circle is still the same. How you crop that image circle doesn't change the lens distortion and subsequent correction.
