Re: Dpreview straightens out distortion correction
In reply to Andy Crowe, May 28, 2010

As a article with a wide audience I believe it should have been stated that geometric distortion is a by product mainly of zoom type designs and that primes don't suffer geometric distortion anywhere near the degree a zoom can. Primes need no software or special glass, its why distortion was not a huge deal back in the film days. Now with super zooms, zooms covering 18-200mm in any format you will have to make many trade-offs in its design no doubt about it. And yep you can cover some of the poor control of aberrations of the lens with software, which I don't have a problem with to a point.

But it should have been stressed the best most expensive (but not always) optical performance comes from prime lens as they don't have to trade off anything for great performance.

Now I must say I am a zoom shooter and prefer zooms over primes, but still the reader should have been fully educated.
