Re: Sony APS-C Zooms

These days, sensors have more resolution than lenses. Especially not in the center. So distortion correction does not have to degrade image quality.

Axtra elements could degrade image quality by adding more chance to have flare - and would make the lens heavier. Doing it electronically is not a bad way at all.

Vignetting is a result of the lens being smaller than others with comparable specifications. Vignetting drives up the ISO at the sides and corners. But the result again is a smaller lens.

The 18-135 is a lot smaller than the CaNikon counterparts (which need low distortion only because they have an OVF which cannot correct distortion).

I think it is good to talk about distortion correction versus vignetting compensation. And in the end it is about the result we get - the image - and not how we get there.
