He's saying that on the ist D you are only using the central portion of the fisheyes image circle where the effect is the least. This reduces the 'fisheye' effect and the results look more like a distorted WA shot than a true fisheye shot. I'm just now playing with the Zenitar 16/2.8. If I compose carefully the shot looks like a very WA shot with little fisheye effect. On a 35mm this would not be the case.
