..and to complete the series, lower right corner (this time focussed at 4\')
100% 17-40 F11 Here I feel the 17-40 looks almost 3D (to me)
100% EF 20 F11 In the very extreme corner the EF20 gives up, (I checked other exposures to make sure the grass head hadn\'t moved in a breeze.)
100% OM21 F11 In this close corner the OM21 is definitely sharpest, but then it has a floating design supposed to give improved performance close up.
It also has a more \"delicate\" look to my eye. (Perhaps the 21/2 is corrected more for close focus and the 21/3.5 is better for infinity?)
