If lens manufactures direct lens aberrations towards the outer most edges of the image circle, then wouldn't it be true that a lens that offers a much larger im age circle would create a sharper image on the film. (i.e. all other things bei ng equal, and no camera movements to loose the center of the image on film) For example, the Nikkor 600mm, 800mm and 1200mm all have image circle that barely f ills the 8x10 film area, however the Fujinon lenses in the same focal length cov ers well over (135%) the 8x10 film area. Which of these two manufacturer would create better images in these focal lengths? Any input would be helpful, thank you.
