Good point. There's no direct reference anywhere which aperture these are.
If you look at the comparison XF 2/18mm to EF 1.8/28 ( shown in http://forums.dpreview.com/forums/readfl...d=40313316 ) the MTF for the Canon lens appears to be at maximum aperture ( source: http://software.canon-europe.com/files/d..._10_EN.pdf ).
If they did an apples-to-apples comparison, their MTFs should be at maximum aperture as well.
